William Davies (1884 – 17 February 1956) was an Australian politician, born in Abertillery in Wales to the coalminer William Davies and his wife Mary, née Williams. As a child he worked in the coalmines, but won a miners' scholarship to a summer school at the University of Oxford, where he became a Methodist lay preacher. He married Edith Hartshorn on 4 August 1903 and the couple moved to New South Wales in 1912, when Davies became a miner in the Wollongong area, soon rising to become an official of the Australian Coal and Shale Employees' Federation.
