Hercules station is a proposed intermodal infill train station and ferry terminal in Hercules, California in Contra Costa County. It is to be the first direct Amtrak-to-ferry transit hub in the San Francisco Bay Area and will be constructed in between the existing Richmond and Martinez stations. By July 2018, three of the station's six construction phases had been complete, including street at Bay Trail approaches. However, no proposed opening date has yet been announced by the City of Hercules.

An infill station is a train station built on an existing passenger rail, rapid transit, or light rail line to address demand in a location between existing stations. Such stations take advantage of existing train service and encourage new riders by providing a more convenient location. Many older transit systems have widely spaced stations and can benefit from infill stations. In some cases, new infill stations are built at sites where a station had once existed many years ago, for example the Cermak–McCormick Place station on the Chicago 'L''s Green Line.
