William Kean (17 March 1871 – 5 January 1954) was a British trade unionist. Born in Sheffield, Kean became a cutler working in silver and a trade unionist. By his early twenties he was secretary of the small Sheffield-based Spoon and Fork Filers, Odd Workers and Stampers Society. From this position, he masterminded a merger of several small unions which formed the National Union of Gold, Silver and Allied Trades (NUGSAT), completed in 1911, and became its first secretary.
