The Hanover Square Rooms or the Queen's Concert Rooms were assembly rooms established, principally for musical performances, on the corner of Hanover Square, London, England, by Sir John Gallini in partnership with Johann Christian Bach and Carl Friedrich Abel in 1774. For exactly one century this was the principal concert venue in London. The premises were demolished in 1900.

Giovanni Andrea Battista Gallini, later known as Sir John Andrew Gallini, was an Italian dancer, choreographer and impresario who was made a "Knight of the Order of the Golden Spur" by the Pope following a successful performance.
