Number 92 Squadron RAF, also known as No. 92 (East India) Squadron, is a test and evaluation squadron of the Royal Air Force currently based at RAF Waddington, Lincolnshire. It traces its lineage back to the Royal Flying Corps, forming as a fighter squadron on 1 September 1917 and deploying to France in July 1918 for four months of combat before the end of the war.

During the Battle of Britain in 1940, No. 92 Squadron operated the Supermarine Spitfire from RAF Biggin Hill as part of No. 10 Group, Fighter Command, defending London and the southeast of England against the Luftwaffe. The squadron accounted for a significant number of enemy aircraft destroyed during the battle. After the battle, it continued to operate Spitfire variants through the remainder of the war, supporting the Allied invasion of Europe and conducting fighter sweeps over France.

Post-war, the squadron served in various roles including time with the Special Operations Executive, before eventually being re-designated and continuing in the fighter and evaluation roles it holds today.
