No. 41 Squadron Royal Air Force is a flying squadron of the Royal Air Force (RAF), currently operating as the Test and Evaluation Squadron (TES) for the RAF's Typhoon, presently based at RAF Coningsby in the English county of Lincolnshire in the United Kingdom. Its current official abbreviated title is 41 TES. The squadron was originally formed in April 1916 (1916-04), during First World War as part of the Royal Flying Corps (RFC), and served on the Western Front as a ground attack and fighter squadron. Disbanded in 1919 as part of the post-war draw down, No. 41 Squadron was re-formed as an RAF squadron in 1923, and remained on home service until 1935, when it was deployed to Aden during the Abyssinian crisis.

During the Second World War, the squadron flew Supermarine Spitfire fighters, and saw action over Dunkirk and the during the Battle of Britain in the early years of the war. Combat operations were flown from Britain over German-occupied Europe during 1941–1944, before the squadron moved to the continent after the Normandy landings. During 1944–1945, the squadron supported the Allied advance into Germany, and it remained there until mid-1946 as part of the occupation force following the end of hostilities. In the post-war years, the squadron was disbanded and re-formed several times, operating a variety of jet aircraft in the fighter, reconnaissance, and interceptor roles. In 2006, the squadron was re-roled as the Fast Jet & Weapons Operational Evaluation Unit. It remained in this role until 2010, when it became the Test and Evaluation Squadron of the Royal Air Force.
