1970–71 Aberdeen F.C. season
The 1970-71 season was Aberdeen's 58th season in the top flight of Scottish football and their 60th season overall. Aberdeen competed in the Scottish League Division One, Scottish League Cup, Scottish Cup, and European Cup Winners' Cup.
Aberdeen finished second in the league behind Celtic and became the first club to be knocked out of European competition in a penalty shoot-out when they lost to Hungarian club Honvéd. Goalkeeper Bobby Clark achieved a record by going 1,155 minutes without conceding a goal in the league, which was surpassed in 2009 by Manchester United goalkeeper Edwin Van der Sar. On 6 February a fire destroyed part of the Main Stand at Pittodrie. The Scottish Cup trophy was saved by firemen, but many historical club artifacts and items of memorabilia were destroyed.
