New Haven State Street station is a commuter rail station located on State Street in downtown New Haven, Connecticut. The secondary railroad station in the city, it is located 0.8 miles (1.3 km) northeast of the much larger New Haven Union Station and is intended to offer easier access to New Haven's downtown business district. It is served by Shore Line East and Hartford Line commuter trains, Amtrak Hartford Line trains, Springfield-terminating Northeast Regional trains, and Valley Flyer trains, and a limited number of Metro-North Railroad New Haven Line trains. Originally proposed in 1996, State Street opened on June 7, 2002. A second platform opened on June 8, 2018, in time for the beginning of Hartford Line service.

The Hartford Line is a commuter rail service between New Haven, Connecticut, and Springfield, Massachusetts, using the Amtrak-owned New Haven–Springfield Line. The project is a joint venture between the states of Connecticut and Massachusetts, with support from the federal government as well. CT Rail-branded trains provide service along the corridor, and riders can use Hartford Line tickets to travel on board most Amtrak trains along the corridor at the same prices. The service launched on June 16, 2018.
