They finished in third position in the 22-team division, missing out on promotion to Cardiff City on goal average.

They entered the 1951–52 FA Cup at the third round proper and lost to Leyton Orient in the fourth.

Twenty-three players made at least one appearance in nationally organised first-team competition, and there were fourteen different goalscorers.

Tommy Briggs was top scorer with 19 goals, of which 18 came in the league.

Birmingham had been in the promotion positions since 22 March and were in second position after their last game of the season, on 26 April, but by the time the last game was played, on 3 May, Cardiff City had beaten Leeds United in their last game of the season to finish level on points with Birmingham with a better goal average.
