The following is a list of managers of Oldham Athletic A.F.C. and all honours won by the club since 1906. Up to September 2022, the club has had 47 different managers, and has not won any major competitions in its history. Joe Royle is the longest serving in Oldham's history, managing 608 games. Royle was manager of the club between 1982 and 1994 in which time he led the club to promotion from the Football League Second Division to the First Division while accumulating 225 total competitive wins—the most by any manager in Oldham's history. He also led the club to two semi-final appearances in the FA Cup and a runners up spot in the 1989–90 Football League Cup as his side lost 1–0 to Nottingham Forest. On 15 March 2009, Royle returned to the club as manager following John Sheridan's departure from the club, before leaving the club again at season's end. Jimmy Frizzell is the second longest serving manager in the club's history, holding the position from 1970 until 1982 (544 games). Both he and Royle are the only managers in Oldham's history with over 500 games and 200 or more competitive victories. Sheridan has had the most spells (six) as Oldham manager, totalling 240 games, and is one of six to manage over 200 first team games. (en)
