The 1971 VFL season was the 75th season of the Victorian Football League (VFL), the highest level senior Australian rules football competition in Victoria. The season featured twelve clubs, ran from 3 April until 25 September, and comprised a 22-game home-and-away season followed by a finals series featuring the top four clubs.

The premiership was won by the Hawthorn Football Club for the second time, after it defeated St Kilda by seven points in the 1971 VFL Grand Final. Hawthorn full-forward Peter Hudson kicked 150 goals for the season, equalling the all-time record set by Bob Pratt (South Melbourne) in 1934.

In 1971, the VFL competition consisted of twelve teams of 18 on-the-field players each, plus two substitute players, known as the 19th man and the 20th 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 22 rounds; matches 12 to 22 were the "home-and-way reverse" of matches 1 to 11.

Once the 22 round home-and-away season had finished, the 1971 VFL Premiers were determined by the specific format and conventions of the Page–McIntyre system.

The consolation night series were held under the floodlights at Lake Oval, South Melbourne, for the teams (5th to 12th on ladder) out of the finals at the end of the home and away rounds.

Final: Melbourne 12.7 (79) defeated Fitzroy 9.9 (63).

• Fitzroy winger Treva McGregor won the 1971, 130-yard Stawell Gift in 11.7 seconds, off a handicap of 7¼ yards.
• Bill Barrot of Richmond and Ian Stewart of St Kilda swap clubs before the start of the 1971 season. Stewart went on to win his third Brownlow Medal at Richmond, while Barrott was so dissatisfied at St Kilda's demands that he play in defence that he requested, and was given, a clearance to Carlton during the season.
• The VFL sold its Harrison House headquarters and moved to 84 Jolimont Street.
• The Round 21 match between Fitzroy and Carlton at Junction Oval was played in a thick fog with terrible visibility – so much so that goal umpires could not see each other's flags, forcing the boundary umpires to convey messages between the goal umpires for scorekeeping purposes.^[1]
• In the Grand Final, Peter Hudson could have broken Bob Pratt's season record of 150 goals except for three incidents:
  • He kicked what would have otherwise been an easy goal into the man on the mark (Barry Lawrence).
  • He kicked a goal on the run that was disallowed because the end of the quarter siren had gone before the ball hit his boot.
  • He ran into an open goal and kicked the ball out of bounds.
• The Committees of the Carlton Football Club and Collingwood decide not to renew the contracts of their respective coaches, Ron Barassi and Bob Rose.

• The 1971 VFL Premiership team was Hawthorn.
• The VFL's leading goalkicker was Peter Hudson of Hawthorn who kicked 150 goals (including 10 goals in the finals).
• The winner of the 1971 Brownlow Medal was Ian Stewart of Richmond with 21 votes.
• South Melbourne took the "wooden spoon" in 1971.
• The reserves premiership was won by Richmond. Richmond 14.14 (98) defeated Essendon 8.18 (66) in the Grand Final, held as a curtain-raiser to the seniors Grand Final at the Melbourne Cricket Ground on 25 September.^[2]
