The Mann & Grimmer M.1 was a British prototype two-seat fighter aircraft of the First World War. It was a single-engined biplane with a radial engine in the aircraft's nose driving two pusher propellers, which was hoped to give a good field of fire for the gunner and high performance. Only one example was built, with no production following.
