Mount Vernon Square is a Washington Metro station in Washington, D.C., on the Green and Yellow Lines. During rush hours, this is the northern terminus for Yellow Line service to Huntington, and trains reverse direction using a pocket track just north of the station. Metro has been running off-peak and weekend Yellow Line trains north to Fort Totten since 2006, and three rush hour only Yellow Line trains per hour between Greenbelt and Franconia-Springfield as part of the Rush Plus service pattern, which began on June 18, 2012. Mount Vernon Square is the least-used station within the Metro system's core section, seeing only 3,813 entries each weekday.
Mount Vernon Square station is located at the border of the neighborhoods of Downtown and Shaw in the northwestern quadrant of Washington. Its namesake, Mount Vernon Square, is located two blocks to the south at the convergence of New York Avenue and Massachusetts Avenues and 7th, 9th, and K Streets. The station's subtitle is derived from the station's location along 7th Street NW, and its close proximity to the Washington Convention Center, although the station is only one of five Metro stations that run underneath 7th Street NW.
Like many other Metro stations in the Washington Metropolitan Area, Mount Vernon Square station has spurred development in its proximity. Most prominent is the Washington Convention Center, although a number of smaller residential and commercial projects have been completed within the surrounding blocks. To the southeast of the station is the Mount Vernon Triangle, a business improvement district (BID) seeing rapid mixed-use growth. To the southwest of the station is the mixed-use CityCenterDC development project, which is home to luxury condominiums and luxury retail franchises such as Louis Vuitton, Moncler, Gucci, Hugo Boss, Tesla, Del Frisco's Double Eagle Steak House, Fig & Olive and other upscale dining and shopping destinations. 
Service began on May 11, 1991. The station mezzanine was renovated in 2003 to coincide with the opening of the Walter E. Washington Convention Center. The renovation included additional faregates and a new street entrance.
On January 7, 2007, the fifth car of a six-car train derailed in the tunnel at the interlocking south of the station, sending twenty people to the hospital for minor injuries and significantly damaging a rail car. Service resumed the next day at 5 AM.
Originally to be named "Federal City College", the station was named Mount Vernon Square - UDC at the time of its 1991 opening, reflecting the establishment of the University of the District of Columbia. The station was renamed Mt Vernon Sq/7th Street-Convention Center in 2001; the "7th Street" helped distinguish that the stop served the new Walter E. Washington Convention Center as opposed to the old Washington Convention Center at 9th Street NW. On November 3, 2011, the station was again renamed, taking "Mount Vernon Square" as the main name, with "7th Street - Convention Center" as a subtitle.
