William John Evans (4 October 1899 – 23 August 1983) was a British trade union leader.
Evans began working for the London North Western Railway in 1916, but almost immediately left to serve in the Royal Navy, as World War I was ongoing.
Demobbed in 1921, he returned to the railways, and joined the Associated Society of Locomotive Engineers and Firemen (ASLEF).
From 1963 to 1969, he was the civil representative on the National Association for Employment of Regular Sailors, Soldiers and Airmen.
[1] Evans also served on the General Council of the Trades Union Congress, and the executive of the International Transport Workers' Federation.
