The 1971 Ibrox disaster was a crush among the crowd at an Old Firm football game, which led to 66 deaths and more than 200 injuries. It happened on 2 January 1971 in an exit stairway at Ibrox Park (now Ibrox Stadium) in Glasgow, Scotland. It was the worst British football disaster until the Hillsborough disaster in Sheffield, England, in 1989.

The stadium's owner, Rangers F.C., was later ruled to be at fault in a sheriff's judgement on one of the deaths. Rangers did not dispute this ruling, and was sued for damages in 60 other cases brought by relatives of the dead.
