Humboldt County (/ˈhʌmboʊlt/ (listen)) is a county located in the U.S. state of California. As of the 2020 census, the population was 136,463. The county seat is Eureka.
Humboldt County comprises the Eureka–Arcata–Fortuna, California, Micropolitan Statistical Area. It is located on the far North Coast of California, about 270 miles (435 km) north of San Francisco. It has among the most diverse climates of United States counties, with very mild coastal summers and hot interior days. Similar to the greater region, summers are extremely dry and winters have substantial rainfall.
Its primary population centers of Eureka, the site of College of the Redwoods main campus, and the smaller college town of Arcata, site of California State Polytechnic University, Humboldt, are located adjacent to Humboldt Bay, California's second largest natural bay. Area cities and towns are known for hundreds of ornate examples of Victorian architecture.
Humboldt County is a densely forested mountainous and rural county with about 110 miles (177 km) of coastline (more than any other county in the state), situated along the Pacific coast in Northern California's rugged Coast (Mountain) Ranges. With nearly 1,500,000 acres (6,100 km2) of combined public and private forest in production, Humboldt County alone produces twenty percent of the total volume and thirty percent of the total value of all forest products produced in California. The county contains over forty percent of all remaining old growth Coast Redwood forests, the vast majority of which are protected or strictly conserved within dozens of national, state, and local forests and parks, totaling approximately 680,000 acres (1,060 sq mi).
The original inhabitants of the area now known as Humboldt County include the Algic Wiyot, Yurok; the Hokan Karuk; and the Athapaskan Hupa, Chilula, Whilkut, Tsnungwe as well as the Eel River Athapaskan peoples, including the Wailaki, Mattole and Nongatl.
Spanish traders made unintended visits to California with the Manila Galleons on their return trips from the Philippines beginning in 1565. The first recorded entry by people of European origin was a landing by the Spanish in 1775 in Trinidad.
The first recorded entry of Humboldt Bay by non-natives was an 1806 visit from a sea otter hunting party from Sitka employed by the Russian American Company. The hunting party included Captain Jonathan Winship, an American, and some Aleut hunters. The bay was not visited again by people of European origin until 1849 when Josiah Gregg's party visited. In 1850, Douglas Ottinger and Hans Buhne entered the bay, naming it Humboldt in honor of the great naturalist and explorer, Alexander von Humboldt, and the name was later applied to the county as a whole.
The area around Humboldt Bay was once solely inhabited by the Wiyot Indian tribe. One of the largest Wiyot villages, Tolowot, was located on Indian Island in Humboldt Bay. Founded around 900 BC, it contains a shell midden 6 acres (2.4 ha) in size and 14 feet (4.3 m) deep. It was the site of the February 26, 1860 massacre of the Wiyot people that was recorded by Bret Harte, then living in Union, now called Arcata. Between 60 and 200 Wiyot men, women, and children were murdered that night in the midst of a religious ceremony. Tolowot is now a restricted site and a National Historic Landmark. In 2019, the island was restored to the Wiyot tribe, and is now known as Tuluwat or Duluwat island.
Humboldt County was formed in 1853 from parts of Trinity County.
State historic landmarks in Humboldt County include Arcata and Mad River Railroad, California's First Drilled Oil Wells in Petrolia, Camp Curtis, Centerville Beach Cross, the city of Eureka, the victorian town of Ferndale, Fort Humboldt, Humboldt Harbor Historical District, the Jacoby Building, The Old Arrow Tree, Old Indian Village of Tsurai, the Town of Trinidad, and Trinidad Head.
On February 5 and 6, 1885, Eureka's entire Chinese population of 300 men and 20 women were expelled after a gunfight between rival Chinese gangs (tongs) resulted in the wounding of a 12-year-old boy and the death of 56-year-old David Kendall, a Eureka City Councilman. After the shooting, an angry mob of 600 Eureka residents met and informed the Chinese that they were no longer wanted in Eureka and would be hanged if they were to stay in town longer than 3 p.m. the next day. They were put on two steamships and shipped to San Francisco. No one was killed in the expulsion. Another Chinese expulsion occurred during 1906 in a cannery on the Eel River, in which 23 Chinese cannery workers were expelled after objections to their presence. However, some Chinese remained in the Orleans area, where some white landowners sheltered and purchased food for the Chinese mineworkers until after racial tension passed. Chinese did not return to the coastal cities until the 1950s.
According to the United States Census Bureau, Humboldt County encompasses 4,052 square miles (10,490 km2), of which 3,568 square miles (9,240 km2) is land and 484 square miles (1,250 km2) is water.
Cape Mendocino is the westernmost point in California (longitude 124 degrees, 24 minutes, 30 seconds). Humboldt Bay, the only deepwater port between San Francisco and Coos Bay, Oregon, is located on the coast at the midpoint of the county.
Humboldt County contains a diversity of plant and animal species, with significant forest and coastal habitats. In coastal areas there are extensive redwood forests. A prominent understory shrub is the toyon, whose northern range limit is in Humboldt County.
Humboldt County's major rivers include (in order of flow – cubic meters per second – from largest to smallest):
The smaller rivers include Redwood Creek, significant due to amount of its flow; the Van Duzen; the Eel River syncline group composed of the South Fork, the North Fork, and the Salt River; the Mattole, Salmon, Elk, Bear, and Little rivers.
Historically, Humboldt County and the entire far north coast have had many earthquakes over 6.0 magnitude.
The 1992 Cape Mendocino earthquakes were a series of three major earthquakes that occurred off the coast of Cape Mendocino, California on April 25 and 26, 1992, the largest being a 7.2. Ninety-five people were injured and property in the county sustained considerable damage.
In 2010, a 6.5 magnitude earthquake struck offshore, 33 mi (53 km) west of Eureka, resulting in only minor injuries and some structural damage to houses and utilities, and no fatalities reported.
In 2022, a 6.4 magnitude earthquake centered approximately 10 miles (16 km) from Ferndale caused damage, especially in Rio Dell.
The town of Arcata is built on top of an accretionary wedge. This was formed by the subduction of the Gorda plate under the North American plate.
The coastal zone of the county experiences very wet, cool winters and dry, mild foggy summers. In the winter, temperatures range from highs of 40–59 °F (4–15 °C) to lows of 32–49 °F (0–9 °C). Coastal summers are cool to mild, with average highs of 60–69 °F (16–21 °C) and frequent fogs. Coastal summer temperatures range from highs of 64–70 °F (18–21 °C) to lows of 46–55 °F (8–13 °C). In the populated areas and cities near the coast, the highest temperatures tend to occur at locations just a few miles inland from Eureka and Arcata, in towns like Fortuna, Rio Dell, and smaller unincorporated communities located somewhat further away from Humboldt Bay. In these locations summer highs are 70–75 °F (21–24 °C). The coastal zone experiences a number of frosty nights in winter and early spring, though snowfall and hard freezes are rare. Coastal winters are cool and wet. Winter rainstorms are frequent, with averages from 30 to 100 inches (760 to 2,500 mm) a year, depending upon elevation.
Inland areas of the county also experience wet, cool winters. Snowfall is common at elevations over 3,000 ft (910 m) throughout the winter months, and is deep enough at higher elevations to have inspired the opening of a small ski lift operation (now defunct) on Horse Mountain, near Willow Creek, for several decades in the late 20th century. Summer displays the sharpest difference between the coastal and inland climates. Inland regions of Humboldt County experience highs of 80–99 °F (27–37 °C) depending on the elevation and distance from the ocean. Occasional summer highs of 100 °F (38 °C) are common in eastern and southern parts of the county including Orleans, Hoopa, Willow Creek, Garberville, Honeydew, and inland river valleys.

Humboldt County children are at greater risk of dangerously elevated blood lead levels than Flint, Michigan's – and almost double that of any other California county measured. The cases are concentrated in Eureka's Old Town and downtown areas.
Humboldt County is known for its impressive redwood trees, and many acres of private redwood timberland make Humboldt the top timber producer in California. The lush river bottoms adjacent to the ocean produce rich, high-quality dairy products. Somewhat further inland, the warmer valleys have historically produced abundant apples and other fruit. More recently vineyards have been planted in the Trinity, Klamath, Mattole and upper Eel river areas.

Further information: Cannabis in California
As part of the Emerald Triangle, Humboldt County is known for its cultivation of cannabis, estimated to be worth billions of dollars. Proposition 215 allows patients and caregivers who are given a doctor's recommendation to legally (State level only) grow up to 99 plants in Humboldt County. However, in the years before Prop 215 (early 1970s – late 1980s), Humboldt County saw a large migration of the Bay Area counter-culture to the region. Many came looking to purchase cheap land, and ended up growing marijuana to pay for their land. Especially around Garberville and Redway, the rural culture and hippie scene eventually collaborated to create a rural hippie community in which marijuana became the center of the economy and the culture. Many people prospered by producing marijuana for California and other states because of its reputation for quality. A Redway radio station, KMUD, in the past has issued warnings and alerts to the region with information on whereabouts of law enforcement on their way to raid marijuana gardens.
The Campaign Against Marijuana Planting is the multi-agency law enforcement task force managed by the California Department of Justice, formed with the prime purpose of eradicating illegal cannabis production in California. The operations began in the late 1970s, named the Northern California Sinsemilla Strike Force in 1979, but the name CAMP became used after its official establishment in 1983. While the influence of CAMP in Humboldt County has waned with decriminalization of marijuana, there is a renewed interest at the state level regarding valid growing permits and environmental concerns. As a result, CAMP is today still used as a policing body, in accordance with the DEA. Yearly CAMP reports, published by the California Department of Justice, Bureau of Narcotic Enforcement (BNE) are available online through Cal Poly Humboldt's Special Collections. Starting in 1983, the annual reports detail the organizational structure and names of individual participants, a summary of the season's activities, tactics, and mention of special successes, trends and hazards.
County officials and the industry have encountered challenges in the transition from an illegal, underground economy to legal recreational cannabis sales that began in California in 2018.
Humboldt County is in California's 2nd congressional district, represented by Democrat Jared Huffman.
In the state legislature, Humboldt is part of the 2nd Senate District, represented by Democrat Mike McGuire, and the 2nd Assembly District, represented by Democrat Jim Wood.
Election audits in the county since 2008 have used a distinctive system which has spread elsewhere. They scan all ballots and release a file of the images with a digital signature, so candidates and the public can recount to find if the official totals are correct. They also release software to let the public tally the images electronically. The first time they did this they found the official software omitted 200 ballots.

From 1920 to 1984, the county was a noted bellwether area, voting for the national winner of every Presidential election. Since 1988, Humboldt has swung heavily to the Democratic Party at the Presidential and congressional levels, and is now one of the most Democratic areas in the state outside the Bay Area and Southern California. The last Republican presidential candidate to win a majority in the county was Ronald Reagan, a Californian, in 1984.
In the late 1990s and early 2000s, Humboldt also had a substantial number of people affiliated with the Green Party, but that number has declined in recent years; however, the Green Party has had its best performance by presidential and gubernatorial candidates of any county in the United States in Humboldt County, with Jill Stein gaining her largest county-level number of votes in Humboldt in 2016.
Humboldt County is known for an unusual number of missing person cases. It was highlighted as part of the 2018 Netflix documentary Murder Mountain.

In the book Lolita by Vladimir Nabokov there is a possible pun using the county's name (Humboldt) in connection to the main character's name (Humbert Humbert). This appears on page 108: "With the help of a guidebook I located [The Enchanted Hunters inn] in the secluded town of Briceland." This 'secluded town' could very well be a reference to the unincorporated Briceland of Humboldt County, making The Enchanted Hunters in 'Humboldt Land', continuing the novel's grotesque fairy-tale veneer.
Humboldt County has eight Indian reservations lying within its borders. Only four other counties in the United States have more: San Diego County, California; Sandoval County, New Mexico; Riverside County, California; and Mendocino County, California. The Hoopa Valley Indian Reservation is the largest in the state of California, a state that generally has small reservations (although numerous) relative to those in other states.
The population ranking of the following table is based on the 2010 census of Humboldt County.
