Thomas Blair (24 February 1892 – 28 August 1961) was a Scottish footballer who played as a goalkeeper.^[4]

Blair was prominent in the 1910s playing for Kilmarnock,^[5] with the culimation of his nine-year spell there being a Scottish Cup win in 1920, lifting the trophy as team captain.^[6][7] He then moved to England with Manchester City,^[8] spending two years there but only the regular in his position in the second campaign. He played on both sides in the Home Scots v Anglo-Scots international trial and conceded only once in each match,^[9][10] but this did not lead on to a full cap for Scotland.

By now in his 30s, Blair accepted an invitation to play in the American Soccer League, appearing for teams including Fall River F.C.^[11] and New Bedford Whalers.^[12][13] After several years in the United States he returned to Scotland with Ayr United (no league appearances recorded) then spent time in Northern Ireland at Linfield before becoming a coach at Dundee United in 1937. That same year he made a final, emergency SFL appearance in a 7–1 defeat to St Bernard's, aged 45.^[14]
