The 1931 Victorian Football League season was the 35th season of the elite Australian rules football competition.

In 1931, the VFL competition consisted of twelve teams of 18 on-the-field players each, plus one substitute player, known as the 19th man. A player could be substituted for any reason; however, once substituted, a player could not return to the field of play under any circumstances.

Teams played each other in a home-and-away season of 18 rounds; matches 12 to 18 were the "home-and-way reverse" of matches 1 to 7.

Once the 18 round home-and-away season had finished, the 1931 VFL Premiers were determined by the specific format and conventions of the Page–McIntyre system. This was the first season to feature the new finals format, with the league predominantly using variations of the Argus System over the previous thirty seasons.

Round 6 was a split round, but the two halves of the round were unusually played almost three weeks apart. Three matches played on King's Birthday Monday (8 June), and the other three matches played Saturday 27 June – the Saturday between Rounds 8 and 9. This means that six teams played their Round 7 and 8 matches before their Round 6 match.

All of the 1931 finals were played at the MCG so the home team in the Semi Finals and Preliminary Final is purely the higher ranked team from the ladder but in the Grand Final the home team was the team that won the Preliminary Final.
