William Mason (1719 – 29 September 1791) was a Christian Calvinist writer from England.

Mason was born in Rotherhithe, south London.^[1] He was a Justice of the Peace and later an acting Magistrate.^[2]

He wrote a number of Christian books, and was twice briefly editor of The Gospel Magazine, immediately before and immediately after Augustus Montague Toplady. He also wrote several hymns, including "The Christian Surrender".

He was originally a follower of John Wesley, but abandoned Wesleyan Arminianism in favour of the Calvinist teachings of George Whitefield. He defined himself as a "Church of England Methodist". As a theological writer, he focussed on doctrinal issues, including justification by faith, predestination and the afterlife.^[3] 

He married Miss Cox when he was 21 and they had a son, Reverend Henry Cox Mason. William Mason died of a stroke at the age of 72.^[4]
