Donald Rex Scott (born 5 November 1929) is a former Australian rules footballer who played with South Melbourne in the Victorian Football League (VFL) during the early 1950s.
Scott played mostly as a ruckman or in defence over the course of his career, which began in 1948 at West Perth.
In his first season, he was selected in the Western Australian interstate team and took part in two victories over Victoria.
His VFL stint lasted five seasons, with South Melbourne failing to make the finals in each.
He returned to West Perth as captain-coach in 1955 and the following year crossed to Swan Districts where he had the same role.
