List of Gillingham F.C. seasons

Twice in the late 1980s Gillingham came close to winning promotion to the second tier of English football, but a decline then set in and in 1993 the club narrowly avoided relegation to the Football Conference.

In 2000, Gillingham reached the second tier of the English league for the first time in the club's history.

The club has won honours at a professional level namely the Football League Fourth Division championship in the 1963–64 season as well as the Football League Two championship in the 2012–13 season.
