Benjamin Cronyn (11 July 1802 – 21 September 1871) was the first bishop of the Anglican Diocese of Huron. A member of the prominent Anglo-Irish Protestant Ascendancy Cronyn family, and a relative of Robert Whitehead, he emigrated to Canada in 1832. He was posted to London, Ontario, where he completed the church building started by his predecessor. In 1844 he relocated the church to a better site, now occupied by St Paul's Cathedral.
