The 9:30 Club, originally named Nightclub 9:30, 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 patrons. 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.
As a special feature, the club, with capacity for up to 1,200 people, has a wheeled stage mounted on rails, which can be moved back and forth as needed. This way, the place can feel as packed with 500 people in attendance as it would during a sold-out, full capacity show.
The 9:30 Club's name was derived from its original street address, as well as the original opening time of 9:30 p.m. Early advertising on D.C.'s WHFS radio featured the slogan "9:30 – a Place and Time!"
