The 1909–10 season was Blackpool F.C.'s 13th season (tenth consecutive) in the Football League. They competed in the twenty-team Division Two, then the second tier of English football, finishing twelfth.

Jack Cox took on the role of player-manager for the first time, succeeding club secretary Tom Barcroft.

Walter Miller was the club's top scorer, with fourteen goals, including a hat-trick against Leeds City at Bloomfield Road on New Year's Day, 1910.^[2]

Blackpool won four of their opening five league games, before failing to win any of the six games to follow. Another sequence of note was a four-game win streak between 26 March and 16 April, which assisted in their mid-table finish. In addition, they beat and drew their two matches against the eventual champions, Manchester City.

The club's FA Cup campaign ended at the first-round stage. After drawing 1–1 with Barnsley at Bloomfield Road on 15 January, they lost the replay 0–6.
