Community Transit (CT) is the public transit authority of Snohomish County, Washington, United States, in the Seattle metropolitan area. It operates local bus, paratransit and vanpool service within Snohomish County, excluding the city of Everett (which is served by the separate Everett Transit system). CT is publicly funded, financed through sales taxes, federal grants, and farebox revenue, with an annual operating budget of $248.6 million as of 2025. In 2025, the system had a ridership of 9,517,700, or about 34,100 per weekday as of the second quarter of 2026, placing it third among transit agencies in the Puget Sound region.

The system, officially the Snohomish County Public Transportation Benefit Area Corporation (SCPTBA), operates a fleet of 257 accessible transit buses, 52 paratransit vehicles, and 333 vanpool vans, maintained at two bus bases in Everett. Service is provided year-round at over 1,600 stops on 33 routes throughout the county public transportation benefit area (PTBA). These include three Swift Bus Rapid Transit lines, local and commuter routes that connect with Link light rail, and service to regional Sound Transit facilities. CT also operates several Sound Transit Express routes that serve Snohomish County, Downtown Seattle, and the Interstate 405 corridor. The agency's microtransit service, Zip Shuttle, operates in four cities.

CT began operation as SCPTBA Public Transit on October 4, 1976, four months after voters approved a ballot initiative to establish and fund a new transit system—the third such attempt to create a PTBA. Renamed Community Transit in 1979, the agency expanded service in its first decades of existence, later taking over King County Metro commuter routes to Seattle in 1989 and adding several cities into its PTBA in the 1980s and 1990s. The agency operated commuter service directly to destinations in Seattle until it truncated most of its routes in September 2024, shortly after Link light rail was extended to Lynnwood City Center station. CT was the first operator of bus rapid transit in Washington state and introduced "Double Tall" double-decker buses on its commuter routes to Seattle in the early 2010s.
