William Hendry Stowell (1800–1858) was a Manx nonconformist minister, college head, writer and periodical editor.
Born at Douglas, Isle of Man, on 19 June 1800, he was son of William Stowell and his wife, Ann Hendry.
His first ministerial charge, at St. Andrew's Chapel, North Shields, extended from February 1821 to 1834, when he was appointed head of Rotherham Independent College, and pastor of Masborough congregational church.
In 1848 Stowell was the pioneer of the "missions to working men", and took part in the concert-hall lectures established by Nathaniel Caine at Liverpool in 1850.
Stowell resigned from Cheshunt College in 1856, and died at his residence, Roman Road, Barnsbury, London, on 2 January 1858.
