James Benjamin McCullagh (1854–1921) was an Anglican missionary in British Columbia; he worked under the supervision of the Church Missionary Society, a Protestant body with an evangelical program and practices.
McCullagh is notable for his linguistic work in translating portions of the Bible and the Book of Common Prayer into the Nisga'a language.
One of these, "Hagaga", is often cited as the first Nisga'a newspaper and as a significant space for discussions about Nisga'a land claim politics.
[1] McCullagh was ordained to the diaconate and priesthood in 1890 by the Bishop of Caledonia.
His missionary and educational work was centered on the mission village of Aiyansh, British Columbia.
