Alexander 'Sandy' McNab (born 27 December 1911 in Glasgow, died September, 1962) was a Scotland international footballer. He played a leading role in two of Sunderland's greatest successes. He was on the pitch for the Championship clincher in 1936, and replaced injured captain Alex Hastings in the 1937 Cup Final.
In 1938, McNab joined West Bromwich Albion for a fee of £7,000 but war intervened and he went to various clubs on loan including 3 appearances for Newport County, Nottingham Forest, Northampton Town and Walsall. He eventually signed for Newport County in 1946. McNab later played for Dudley Town and managed Northwich Victoria from 1948-49 before eventually retiring in 1952.
