John Robertson Hare, OBE (17 December 1891 – 25 January 1979) was an English actor, who came to fame in the Aldwych farces. He is remembered by modern audiences for his performances as the Archdeacon in the popular BBC sitcom, All Gas and Gaiters.

Short in stature and of unheroic appearance, Hare made his stage career in character roles. From his early days as an actor he was cast as older men. One of his favourite parts, which he played in the provinces before achieving West End success, was "Grumpy", a retired lawyer, in which he toured before the First World War.
