Henry Wace (10 December 1836 – 9 January 1924) was an English Anglican priest and ecclesiastical historian who served as Principal of King's College, London, from 1883 to 1897 and as Dean of Canterbury from 1903 to 1924.

He is described in the Dictionary of National Biography as "an effective administrator, a Protestant churchman of deep scholarship, and a stout champion of the Reformation settlement".

His best-known work is the Dictionary of Christian Biography and Literature to the End of the Sixth Century A.D., with an Account of the Principal Sects and Heresies, written in collaboration with William Smith.

He was appointed Prebendary of St Paul's Cathedral in 1881 and received the honorary freedom of the City of Canterbury in 1921.

In 1922, he played an important role in the foundation of the Bible Churchmen's Missionary Society and was its Vice-President from 1923 until his death on 9 January 1924, following a road traffic accident.
