The 1976 SANFL Grand Final was an Australian rules football game contested between the Port Adelaide Football Club and the Sturt Football Club, held at the Football Park in Adelaide on the 25 September 1976. It was the 55th annual Grand Final of the South Australian National Football League, staged to determine the premiers for the 1976 SANFL season. The match, attended by 66,897 ticketed spectators, was won by Sturt by a margin of 41 points, marking the club's twelfth premiership victory.
The Grand Final sold a state record 66,987 tickets but when the SANFL ran out they opened Football Park's gates for free and the crowd grew by an estimated 15,000. The gates were shut by police 90 minutes before the bounce as spectators were being crushed. Subsequently, the police allowed thousands of spectators onto the field to sit along the fence to prevent any further physical injuries.
