Jeriah Swetland (April 1817–November 24, 1906) was an American businessman and local politician in nineteenth-century central Ohio. A native of Springfield, New Hampshire, Swetland was the ninth of ten children born to Roswell and Naomi (Rockwell) Swetland. At the age of nineteen, he left home for an apprenticeship in the harnessmaking and saddlemaking trades. On May 23, 1841, he married the former Arabella Fellows, who bore him three children. Two years later, he left New Hampshire to settle in London, Ohio, where he began to conduct business; between 1847 and 1856, he moved at various times to Pickaway County, Mount Sterling, and again to London, where he joined in partnership with William Chandler for a ten-year period.
