William Harcus (c. 1823 – 10 August 1876) was a Congregationalist minister in England and South Australia, where he later turned journalist and editor.
While in England he made literary contribution to several journals, notably a series "Lives of the Apostles" for the Christian Witness.
[1] In 1860 he emigrated with his wife and children to South Australia, where he was appointed minister of the Clayton Congregational Church in a part of Kensington now known as Beulah Park.
In 1872, when Griffiths left for England, Harcus served in an honorary capacity for some six months until a permanent replacement, Thomas Hope (1846–1916), was appointed.
[1] Aside from serious journalism, he was a capable poet and humorous writer, noted for his "Laconic Leader" columns in The Advertiser.
