Much of the physical construction of the station was complete by 1980, and its opening was initially to occur in 1983. However, due to litigation surrounding where the line would terminate in Prince George's County, planning and construction of the Green Line halted in 1981 and would not resume until 1985. The station opened on December 28, 1991, and coincided with the completion of approximately 2.88 miles (4.63 km) of rail southeast of the L'Enfant Plaza station and the opening of the Anacostia and Navy Yard – Ballpark stations.

The station was renamed Waterfront–SEU in 1997, referring to the nearby Southeastern University. Southeastern University closed in 2009, and the station reverted to the Waterfront name on November 3, 2011.

The station has an island platform with a single escalator bank entrance north of the intersection of 4th and M Streets.
