Rev. Theodore Percival "Percy" Wilson (1819 - 8 August 1881), generally known as T. P. Wilson was an Anglican priest and author known for his pioneering, albeit brief, work in Adelaide, South Australia. His parents and his four younger siblings emigrated to South Australia aboard Duke of Roxburghe in 1838. Wilson completed his master's degree at Brasenose College, Oxford, and was ordained a priest of the Church of England. He was sent out to Tasmania, where in 1845 he accepted a call to take over the newly built St John's Church, Adelaide, but instead returned to England on account of his wife's illness.
