William Hobart Hare (1838-1909) was an American bishop of the Protestant Episcopal Church, son of George Emlen Hare. He was born at Princeton, N. J., and was educated at the University of Pennsylvania. He preached in Philadelphia until 1870, was for three years the general agent of the foreign committee of the board of missions, and in 1872 was elected Missionary Bishop of Niobrara. He came to Yankton, Dakota Territory in 1873 and his diocese in 1883 was extended to include all of the Dakota Territory. He wrote several pamphlets on missionary work in the West.
He was one of the leading missionaries in America and was called “the Apostle of the West” for his dedicated work in the rural Dakotas among pioneers and Native Americans.
