Alexander McMahon (16 October 1870 – 25 January 1916) was a Scottish footballer who spent most of his career with Celtic.

[4] His first moment of glory came in the 1892 Scottish Cup Final replay, when he scored two goals in the 5–1 victory over Queen's Park.

[1] The advent of professionalism in Scotland the following year stemmed the southward drift and ensured players such as McMahon could earn sufficient remuneration for their talents by staying in their native country.

[1][6][7][8] McMahon eventually left Celtic in 1903, joining Partick Thistle[9] where he played little due to injury and retired a year later.

[10] In May 2015, a biography, Sandy McMahon And The Early Celts by Celtic historian David Potter, was published.
