The Nightclub 9:30, originally named and still commonly referred to as the 9:30 Club, also known simply as the 9:30, is a nightclub and concert venue in Washington, D.C., which was originally housed in the ground floor rear room of the Atlantic Building at 930 F Street NW, in the city's downtown area, where it opened on May 31, 1980, with a legal standing capacity of only 199. In 1996, due to its increasing prominence, the club was moved to a roomier space, its current location at 815 V Street NW, where it anchors the eastern end of the U Street Corridor.
