Alonzo Barnard (1817–1905) was a Presbyterian missionary to Native Americans. He helped people escape slavery and taught formerly enslaved people in Ontario, Canada. He met his wife Sarah Philena Babcock Barnard (1819–1853) at Oberlin College and they worked together as missionaries and abolitionists with other graduates from Oberlin. Called the "Oberlin Band", they were led by Rev. Frederick Ayer. They worked initially for the Western Evangelical Missionary Society, and then the American Missionary Association after 1846. He ran one of the first printing presses in Minnesota, which was used to print books in the Ojibwe language. He established several mission stations and was a fund-raiser for the mission.
