• Source: List of Leyton Orient F.C. seasons

This is a list of all the seasons played by Leyton Orient Football Club in English football. The club was formed in 1881 as Glyn Cricket Club, and started a football section named Orient Football Club in 1888. Friendly matches were played against local sides until the club was elected into the Clapton & District League for the 1893–94 season.
Leyton Orient is the second oldest football club in London, behind Fulham, and was elected to The Football League for the 1905–06 season. The club has undergone a number of name changes during its history: from Orient to Clapton Orient in 1898; to Leyton Orient in 1946; a reversion to Orient in 1966, then a return to the Leyton Orient name in 1987. The club has reached the top flight of English football once in its history, a single season in Division One in 1962–63 which ended in relegation. Leyton Orient's best performance in the FA Cup was in reaching the semi-final stage in 1977–78.
This list includes the abandoned 1939–40 season and the unofficial Second World War leagues.
