Flight lieutenant is a junior officer rank used by some air forces, with origins from the Royal Air Force. The rank originated in the Royal Naval Air Service (RNAS) in 1914. It fell into abeyance when the RNAS merged with the Royal Flying Corps during the First World War but was revived in 1919 in the post-war RAF. The rank is used by air forces of many countries that have historical British influence.

The Royal Air Force (RAF) is the air and space force of the United Kingdom, British Overseas Territories and Crown Dependencies. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by merging the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has played a significant role in British military history. In particular, during the Second World War, the RAF established air superiority over Hermann Göring's Luftwaffe during the Battle of Britain, and led the Allied strategic bombing effort.
