1949–50 Birmingham City F.C. season

The 1949–50 Football League season was Birmingham City Football Club's 47th in the Football League and their 28th in the First Division. They were bottom of the 22-team division by the end of August, a position which they retained for all but three weeks of the season, so were relegated to the Second Division for 1950–51. They entered the 1949–50 FA Cup at the third round proper and lost in that round to Swansea Town.

Twenty-nine players made at least one appearance in nationally organised competition, and there were nine different goalscorers. Goalkeeper Gil Merrick was ever-present in the 43-game season, and Jimmy Dailey was leading goalscorer with only nine goals, all scored in the league.
