The 1918 VFL season was the 22nd season of the Victorian Football League (VFL), the highest level senior Australian rules football competition in Victoria.
Played during the final year of World War I, eight of the league's nine senior clubs competed, an increase of two from the previous year with only Melbourne absent. The season ran from 11 May until 7 September, and comprised a 14-game home-and-away season followed by a finals series featuring the top four clubs.
The premiership was won by the South Melbourne Football Club for the second time, after it defeated Collingwood by five points in the 1918 VFL Grand Final.
In 1918, the VFL competition consisted of eight teams of 18 on-the-field players each, with no "reserves", although any of the 18 players who had left the playing field for any reason could later resume their place on the field at any time during the match.
Each team played each other twice in a home-and-away season of 14 rounds.
Once the 14 round home-and-away season had finished, the 1918 VFL Premiers were determined by the specific format and conventions of the amended "Argus system".

All of the 1918 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.
