Alistair Shewan (5 August 1940 – 29 January 2024) was a Scottish footballer who played as a left-back.^[1][2] He joined Aberdeen, his only club at the professional level, in 1960, and was almost ever-present from 1963 until his departure in 1969. He was on the losing side in the 1967 Scottish Cup Final.

In the summer of 1967, Aberdeen came to America, playing as the Washington Whips in the fledgling United Soccer Association. The Whips won the Eastern Division and met the Los Angeles Wolves (actually the Wolverhampton Wanderers) in the championship game. In the 122nd minute of extra time with the match tied 5–5, Shewan scored an own goal, giving Los Angeles a 6–5 win and the title.

After leaving Aberdeen, Shewan spent time in Australia then played for, and later managed, Elgin City, when they played in the Highland Football League. Shewan, described as a "no-nonsense left-back", is a member of Aberdeen Football Club's Hall of Fame, inducted in 2004.

Shewan died on 29 January 2024, at the age of 83.^[3][4]
