WestCAT is a public transportation service in western Contra Costa County (north of Oakland, CA). It is a service of the Western Contra Costa Transit Authority.

The Western Contra Costa County Transit (WestCAT) was established in August 1977 as a Joint Exercise of Powers Agreement between Contra Costa County and the cities of Hercules and Pinole. It was created with the purpose of owning, operating and administering a public transportation system serving the area between the Richmond/El Sobrante border to the west and the Al Zampa Memorial Bridge to the east. WestCAT is governed by a 7-member Board of Directors and supported by professional staff of seven. The two cities of Pinole and Hercules are each represented by two board members, while the unincorporated communities of Crockett, Rodeo, and Montalvin Manor each have one representative, appointed by the Contra Costa Board of Supervisors.

WestCAT's fleet started out with shuttle vans, and then using buses made by El Dorado National and Thomas Built Buses. Now, WestCAT runs an almost all Gillig fleet, ranging from 19 Gillig Phantoms, to 18 Gillig Low Floors. WestCAT also has five Motor Coach Industries (MCI) over-the-road coaches and three Alexander Dennis Enviro500 double-decker buses for use on the LYNX. In addition, WestCAT has 10 Ford E-450 Paratransit vans, and 2 Toyota Camry hybrid electric sedans used for Dial-A-Ride.
