Peter Russell Weir (born 18 January 1958) is a Scottish former footballer, best known for his time with Aberdeen, who played as a winger.

Having been a supporter of Aberdeen as a boy, Peter joined the club from St Mirren in 1981 for £300,000 plus Ian Scanlon, which was then a club record;^[2] Alex McLeish, who had attended Barrhead High School and played in youth teams alongside Weir, was already at the club.^[3] He had been brought to St Mirren in 1978 by Alex Ferguson who left the Paisley club within days,^[4] but soon became manager of Aberdeen and sought to make his former signing part of his new team.

In December 1987, Weir left the Dons to move across the border to sign for Leicester City^[2] for £80,000. Upon leaving Leicester in 1989, he returned to St Mirren and later played for Ayr United.
