William John Woodcock (c. 1808 – 25 May 1868), generally referred to as W. J. Woodcock or John Woodcock, was an Anglican priest remembered as the first curate of Christ Church, North Adelaide in South Australia.
Woodcock was born in England, and studied at the Church of England Missionary College for missionary work, in pursuit of which he was, under the auspices of the Society for the Propagation of the Gospel, in India at the Tinivelley Mission from 1835 to 1837, when ill-health forced him to return to England, where he married. Later that year he was sent to Jamaica, where he remained until 1840, when again he was forced by poor health to repatriate.
He spent a few months as curate of Kendal, then ministered at Witherslack, before migrating with his wife and five children to the young colony of South Australia on the barque Emu, accompanied by Rev. James Pollitt and his family, arriving in May 1846 with very flattering testimonials from Colonel Gawler. The first Sunday in Adelaide he preached a well-received sermon at Trinity Church, and was shortly appointed to St. John's church, where he remained for around three years. He preached the evening service of the consecration of Trinity Church on 30 July 1848.
The foundation stone of Christ Church, North Adelaide was laid on 1 June 1848, and Woodcock was appointed to the church in May 1849, Matthew B. Hale, Archdeacon of Adelaide, being appointed to St. John's in his place. The church was opened and consecrated on 20 December 1849, and there Woodcock served for the rest of his life.
He was instituted into the office of Archdeacon of Adelaide on 20 January 1857 when Rev. M. B. Hale was appointed Bishop of Perth. With this appointment he became ex officio a Governor of St. Peter's College, and one of the Attorneys for the Society for the Propagation of the Gospel in Adelaide, as well as Examiner of prospective deacons and priests.
