William Dealtry (1775–1847) was an English clergyman of evangelical views, who became archdeacon of Surrey and a Fellow of the Royal Society.
He was the younger son of an old Yorkshire family, from whom he inherited at his father's death a small landed property.
Belonging to the evangelical party in the Church of England, he took part in the controversy which arose on the formation in 1810–12 of the British and Foreign Bible Society, which he supported.
[2] On 25 February 1830 Dealtry received a prebendal stall at Winchester Cathedral, and was made chancellor of the diocese; in 1845 he was appointed archdeacon of Surrey.
He also published sermons and charges, and pamphlets in defence of the British and Foreign Bible Society.
