During the 1991–92 English football season, Millwall F.C. competed in the Football League Second Division.
In the 1991–92 season, Millwall were looking to challenge for automatic promotion but started the campaign poorly with 1 win from their first 7 league games which saw them in relegation zone near the end of September and even though their form slightly improved onwards, manager Rioch was sacked after a 6–1 defeat at Portsmouth and Mick McCarthy took over as player-manager and kept them up from possible relegation, with Millwall finishing in a disappointing 15th place.
