William Wilson Cash, DSO, OBE (12 June 1880 – 18 July 1955), was an Anglican Bishop in the middle part of the 20th century. Cash was unusual for a bishop of a diocese in England at that time in that he was not public school nor Oxbridge educated.

Wilson Cash was educated in Sale and became a CMS missionary in 1902. Ordained in 1911, he was appointed a Chaplain to the Forces in 1916. He greatly impressed the Chaplain-General at his interview who described Cash as "A1, a Man". Cash served in Egypt and Mesopotamia and ended the War with a DSO and OBE and was five times Mentioned in Despatches. He preached at the Thanksgiving Service in St George's Cathedral following General Allenby's triumphant march into Jerusalem. Afterwards he was General Secretary of the Society until his elevation to the episcopate as Bishop of Worcester in 1941.
