William McNair (29 April 1885 – ?) was a Scottish footballer who played as a centre forward or outside left for Celtic, Tottenham Hotspur and Aberdeen.
McNair started his career in Scotland with Forth Rangers.[1] He signed for Celtic in January 1905 and played his first game for the club on 11 March 1905 in a friendly, then was known to have played two further matches including a single Scottish Division One appearance against Motherwell in August 1905,[1] before moving out on loan to second-tier Hamilton Academical in December of the same year.[2] He then had a season-long loan to East Stirlingshire in September 1906.[3]
In May 1907, McNair moved to London to play for Tottenham Hotspur for one season, signed as cover for Vivian Woodward. His debut occurred on 2 September 1907 in an away game against Queens Park Rangers in the Southern Football League which finished as a 3–3 draw. In one season with Tottenham he went on to record 27 appearances and seven goals in all competitions.
After one season with Aberdeen,[4] McNair moved south again to play for Reading, his debut occurring on 8 September 1909 in a Southern League game against Leyton.[5] He also played for non-league Alloa Atheltic.[3]
