The Queen's Theatre was a London theatre established in 1867 on the site of St Martin's Hall, a large concert room that had opened in 1850. It stood on the corner of Long Acre and Endell Street, with entrances in Wilson Street and Long Acre. The site is within the modern Camden, part of Covent Garden.

Long Acre is a street in the City of Westminster in central London. It runs from St Martin's Lane, at its western end, to Drury Lane in the east. The street was completed in the early 17th century and was once known for its coach-makers, and later for its car dealers.
