Admiralty Arch is a large office building in London which incorporates an archway providing road and pedestrian access between The Mall, which extends to the southwest, and Trafalgar Square to the northeast. It was designed by Sir Aston Webb, constructed by John Mowlem & Co and completed in 1912. It adjoins the Old Admiralty Building, hence the name.

The building was commissioned by King Edward VII in memory of his mother Queen Victoria, although he did not live to see its completion.
