Norton Strange Townshend (December 25, 1815 - July 13, 1895) was a United States Representative from Ohio. Born in Clay Coton, Northamptonshire (England), in 1830 he migrated to the United States with his parents, who settled in Avon, Ohio. He educated himself by the use of his father's library, taught a district school for a short time, and was graduated from the University of Physicians and Surgeons in New York in 1840.
Townshend was a delegate to the World's Antislavery Convention in London in 1840, studied medicine in the hospitals of London, Paris, Edinburgh, and Dublin, and in 1841 engaged in the practice of medicine in Avon, Ohio. He moved to Elyria, Ohio and was a member of the Ohio House of Representatives in 1848 and 1849. He was a delegate to the State constitutional convention in 1850, and was elected as a Democrat to the Thirty-second Congress (March 4, 1851-March 3, 1853).
In 1854 and 1855, Townshend was a member of the Ohio Senate and was medical inspector of the United States Army with the rank of lieutenant colonel from 1863 to 1865. He engaged in agricultural pursuits near Avon, was director of the State board of agriculture from 1858 to 1869 and 1886 to 1889, was professor of agriculture in Iowa Agricultural College in 1869, and was appointed in 1870 as one of the first trustees of Ohio Agricultural and Mechanical College. He resigned in 1873 to become professor of agriculture in the new State college and served until his resignation in 1892, when he became professor emeritus. Townshend died in Columbus, Ohio in 1895; interment was in Protestant Cemetery, Avon Center, Ohio.
