The Nomlaki (also Noamlakee, Central Wintu, Nomelaki) are a Wintun people native to the area of the Sacramento Valley, extending westward to the Coast Range in Northern California. Today some Nomlaki people are enrolled in the federally recognized tribes: Round Valley Indian Tribes, Grindstone Indian Rancheria or the Paskenta Band of Nomlaki Indians. The Nomlaki were bordered by the Wintu (Wintun) in the north, the Yana in the northeast and east, the Konkow (Maiduan) in the east, the Patwin (Wintun) in the south, and the Yuki in the west.
There are two main groups:
The Nomlaki spoke a Wintuan language known as Nomlaki. It was not extensively documented, however, some recordings exist of speaker Andrew Freeman and Sylvester Simmons.
Estimates for the pre-contact populations of most native groups in California have varied substantially. (See Population of Native California.) Alfred L. Kroeber (1925:883) put the combined 1770 population of the Nomlaki, Wintu, and Patwin at 12,000. Sherburne F. Cook (1976:180-181) estimated the combined population of the Nomlaki and northern Patwin as 8,000. Walter Goldschmidt (1978:341) thought that the pre-contact population of the Nomlaki was probably more than 2,000.
Kroeber estimated the population of the Nomlaki, Wintu, and Patwin in 1910 as 1,000.
The US federal government restored the Paskenta Band of Nomlaki Indians to full tribal status in 1994. They were able to acquire land, the Paskenta Rancheria (), and establish the Rolling Hills Casino outside of Corning, California. Nomlaki people are also enrolled in the federally recognized Grindstone Indian Rancheria and Round Valley Indian Tribes.
