| Continentalcup1: | New Club in League |
| Nextseason: | 1913–14 |
The 1912–13 season was the 25th season of The Football League, a league of professional association football clubs in England and Wales.
Beginning in the 1894–95 season, clubs finishing level on points were separated according to goal average (goals scored divided by goals conceded). In case one or more teams had the same goal difference, this system favoured those teams who had scored fewer goals. The goal average system was eventually scrapped beginning with the 1976–77 season.
During the first six seasons of the league, (up to the 1893–94 season), re-election process concerned the clubs which finished in the bottom four of the league. From the 1894–95 season and until the 1920–21 season the re-election process was required of the clubs which finished in the bottom three of the league.
