Frederick Stephen Turnbull (1888–1959) was an English professional footballer who played at inside-forward for Coventry City and Southampton in the 1910s.
After two years playing reserve team football for Newcastle,[1] he joined Coventry City of the Southern League in the summer of 1911.
On 13 January 1912, Turnbull scored the opening goal in a 2–0 FA Cup victory at Southampton (with the other from Harry Parkes), although Coventry went out in the next round, losing 5–1 to Manchester United.
In October, with the "Saints" only winning one of their first eight matches, McIntyre returned to Coventry to sign Turnbull in an effort to improve the team's goal-scoring.
Despite scoring only one further league goal, Turnbull retained his place in the team for the remainder of the season, other than a spell out injured in January/February when he was replaced by Archie Small.
