Thomas Rees (1777 – 1 August 1864), Welsh Nonconformist divine, was a Unitarian minister and scholar.
Rees was educated at the Presbyterian College, Carmarthen. He entered the Unitarian ministry in 1807 at the Newington Green Unitarian Church, London. He went to Southwark in 1813, earned the degree of LL.D. of Glasgow in 1819, and went to Stamford Street, Blackfriars, in 1823.
He had great knowledge of the history of anti-trinitarian opinion, especially of the 16th century. He published papers, chiefly in the Monthly Repository between 1818 and 1822, on such subjects as Faustus Socinus and Francis David, including The Italian Reformation, Memoirs of the Socini. Financial troubles drove him to Spain in 1853, and he died in obscurity in Brighton.[1]
