William Jameson Thompson, CBE (27 October 1885 – 17 November 1975) was a long-serving Anglican bishop^[1] who spent much of his career in Iran (then Persia).^[2]

Educated at Monkton Combe School^[3] and Trinity College, Cambridge, he served in the Great War as an officer in the Royal Engineers. Ordained in 1921,^[4] he was initially principal of the Stuart Memorial College, Isfahan^[5] then archdeacon of the area until his elevation to the episcopate as the third Anglican bishop of Iran in 1935. He retired in 1960^[6] and died 15 years later.

William Thompson's daughter, Margaret, married Hassan Dehqani-Tafti, who succeeded him as Bishop in Iran; their daughter in turn, Guli Francis-Dehqani, became the first bishop of Loughborough and subsequently bishop of Chelmsford.
