William David Davies, often known as W. D. P. Davies, (18 January 1897 – 7 July 1969) was a Welsh Presbyterian minister and writer on theological topics. After becoming the first Welsh student to obtain a Bachelor of Divinity degree from the University of Oxford, he turned down an offer to become a theology tutor at Oxford, along with a college fellowship, preferring to become a Presbyterian minister. He wrote various theological works and was regarded as an excellent scholar as well as a powerful preacher.
