Flight lieutenant (Flt Lt in the RAF and IAF; FLTLT in the RAAF and RNZAF, formerly F/L in the RCAF) is a junior commissioned rank in the Royal Air Force and the air forces of many Commonwealth countries. It ranks above flying officer and immediately below squadron leader. The name of the rank is the complete phrase; it is never shortened to "lieutenant". In RAF informal usage, a flight lieutenant is sometimes referred to as a "flight lieuy".

It has a NATO ranking code of OF-2, and is equivalent to a lieutenant in the Royal Navy or a captain in the British Army or the Royal Marines.

The equivalent rank in the Women's Auxiliary Air Force (WAAF), Women's Royal Air Force (WRAF) (until 1968) and Princess Mary's Royal Air Force Nursing Service (PMRAFNS) (until 1980) was flight officer.

On 1 April 1918, the newly created RAF adopted its officer rank titles from the British Army, with Royal Naval Air Service lieutenants (entitled flight lieutenants and flight commanders) and Royal Flying Corps captains becoming captains in the RAF. In response to the proposal that the RAF should use its own rank titles, it was suggested that the RAF might use the Royal Navy's officer ranks, with the word "air" inserted before the naval rank title. For example, the current rank of flight lieutenant would have been "air lieutenant". Although the Admiralty objected to this simple modification of their rank titles, it was agreed that the RAF might base many of its officer rank titles on navy officer ranks with differing pre-modifying terms. It was also suggested that RAF captains might be entitled flight-leaders. However, the rank title flight lieutenant was chosen as flights were typically commanded by RAF captains and the term flight lieutenant had been used in the Royal Naval Air Service. The rank of flight lieutenant has been used continuously since 1 August 1919.

Henry "Harry" Hardy (14 January 1895 – 17 February 1969) was a football player from Stockport, England, regarded as one of the best players that Stockport County have ever had. He was the first, and to date the only, player for Stockport County to win an England cap. Hardy made 207 appearances for Stockport. He made his unremarkable debut against Cardiff on 4 September 1920, conceding three goals. He then went on the make 170 consecutive appearances for the club before he missed his first County game, a 1-1 draw with Southampton on 11 October 1924, due to his involvement with the Football League representative side. He also played for Everton F.C. and Bury F.C..

He is thought of as County's best ever goalkeeper. His statistics, though, in the Hatters' Division Three (North) championship season in 1922, are remarkable.

Hardy was an ever-present conceding just 21 goals, a club record that stands to this day. He kept 23 clean sheets in his 38 games, which included a quite incredible 20 from his side's opening 27 games of the campaign

Officially recorded by the Indian Air Force as killed in action, Flt Lt Tambay is believed to have been one of the five pilots reported by Pakistan Observer to have been captured alive on 5 December 1971. However, although a number of reports from eye witnesses have subsequently suggested that Flt Lt Tambay was indeed captured alive, he was not repatriated at the end of the war, while the Pakistan Government denies having in their possession any Indian Prisoners of War from the 1971 war,. making him one of The missing 54 Indian defence personnel from the war who are believed to be in Pakistani custody.
