Greater Bridgeport is the metropolitan area centered on the city of Bridgeport in the U.S. state of Connecticut. The area is located in Southwestern Connecticut. In its most conservative form the area consists of the city of Bridgeport and five surrounding towns—Easton, Fairfield, Monroe, Stratford, and Trumbull. This definition of the Bridgeport area has a population of more than 305,000 and is within the Bridgeport-Stamford-Norwalk-Danbury metropolitan statistical area (Bridgeport metropolitan area), which consists of all of Fairfield County, Connecticut. The estimated 2015 county population was 948,053. The area is numbered as part of the New York-Newark Combined Statistical Area NY-NJ-CT-PA by the United States Census Bureau.
The combined metropolitan area is the fourth largest of New England (behind the Boston, Providence, and Hartford areas). The area includes Connecticut's two largest cities: Bridgeport and Stamford. As of 2022 the Bridgeport-Stamford-Norwalk-Danbury area has been split into two different Connecticut regions (the state equivalent to counties), the Western Connecticut region (including Stamford, Norwalk and Danbury), and Metropolitan Connecticut (MetroCOG), consisting of the five towns of Greater Bridgeport. The region is home to one of the largest concentration of corporate headquarters in the nation.
The smallest official definition of Greater Bridgeport is the area under the authority of the Greater Bridgeport Regional Planning Agency, which oversees transportation, land use and economic development planning for its member towns. The region consists of the six towns indicated in the introduction.
The Bridgeport Labor Market Area includes the core region above and also extends northeast into Milford and the Lower Naugatuck Valley (including Ansonia, Beacon Falls, Derby, Oxford, Seymour, and Shelton) for a total of 13 towns.
The urbanized areas of Stamford and Bridgeport are contiguous and considered by the U.S. Census Bureau as a single urban core. The towns containing this merged urbanized area, plus surrounding towns with significant commuter interchange to the central towns, are grouped together as the Bridgeport-Stamford-Norwalk New England City and Town Area. The area contains 25 towns and includes the Greater Bridgeport Region, the Gold Coast, the Lower Naugatuck Valley, and the additional outlying towns of Milford, Newtown, Redding, Ridgefield, Southbury, and Woodbridge. As of the 2000 census, the population of the NECTA was 892,283
A slightly smaller definition known as the Southwest Service Delivery Area consists of the Greater Bridgeport Region, the Lower Naugatuck Valley (including Oxford), the Gold Coast, and the town of Milford (20 towns).
The MSA associated with Bridgeport is the Bridgeport–Stamford–Norwalk–Danbury MSA and consists of the entirety of Fairfield County with 23 towns. While statistically similar in terms of population and extent to the NECTA definition, the MSA includes the city of Danbury and its suburbs, and excludes the Valley region.
The extended Greater Bridgeport area is home to multiple Fortune 500 companies, including Emcor, Xerox, and Booking Holdings in Norwalk, Charter Communications, Syncrony Financial, United Rentals, and Frontier Communications in Stamford, XPO Logistics in Greenwich, and the New England regional base of M&T Bank in Bridgeport (company based in Buffalo, NY).  The coastline portion of the metropolitan area, which is Fairfield County, is known as the Gold Coast, is the densest concentration of wealth in the US, being home to hedge funds, some of the wealthiest towns in the country, commuter Wall Street executives and wealthy WASP families. 
The Greater Bridgeport area, particularly Stamford, is home to WWE, NBC Sports Group, along with their studios,CBS Sports HQ, A&E Networks also has a presence there, all due to Connecticut tax incentives. Blue Sky Studios was based in Greenwich until being closed by Disney in 2022. The Maury, Jerry Springer Show and Steve Wilkos show are also shot in downtown Stamford.
Many towns in the area were once home to heavy industry, and Bridgeport was the state's chief manufacturing city by output and value of goods. Despite a corporate exodus due to deindustrialization, (including the General Electric factory and the Columbia Pictures Processing Plant) nearby Stratford continues to be home to Sikorsky Aircraft and Shelton home to Hubbell Incorporated.

The Bridgeport and Stamford stations are also served by Shore Line East and Amtrak rail service.
The metropolitan area is served by multiple different bus operators for public transit. The Greater Bridgeport Transit Authority operates from downtown near the train station and serves Bridgeport and the surrounding towns of Trumbull, Stratford, Milford, Westport, Fairfield, Shelton and Monroe, which works in conjunction with the Norwalk and Milford Transit.

Talks about commercial services returning to Sikorsky Memorial Airport have been going on for years. Built in the 1920s on Avon Field, located in Stratford and previously owned by the City of Bridgeport (until bought by the Connecticut Airport Authority), the airport ceased commercial flights in 1999, along with the demolition of the passenger terminal.
