William Aitchison Moffat (1900 – 1974) was a Scottish footballer who played mainly as an inside right. He began his senior career with Hamilton Academical in 1922 and remained with them for almost a decade, becoming club captain. In October 1931 he was selected for the Scottish Football League XI and also passed the milestone of 300 league appearances for Accies. Within weeks he had moved on to their Lanarkshire derby rivals Motherwell, at that time regularly challenging for the title but yet to win it.
