The Royal Aquarium and Winter Garden was a place of amusement in Westminster, London. It opened in 1876, and the building was demolished in 1903. The attraction was located northwest of Westminster Abbey on Tothill Street. The building was designed by Alfred Bedborough in an ornamental style faced with Portland stone. The Aquarium Theatre was located in the west end of the building and was renamed the Imperial Theatre in 1879. Methodist Central Hall now occupies the site.
