SS Merchant was an American iron–hulled passenger and package freighter in service between 1862 and 1875. The first iron–hulled merchant ship built on the Great Lakes, she was built in 1862 in Buffalo, New York, by the David Bell shipyard, out of components manufactured in Black Rock, New York, and Philadelphia, Pennsylvania. She was built for James C. and Edwin T. Evans of Buffalo, under whom she carried passengers and freight. Merchant made her maiden voyage in August 1862, sailing from Buffalo to Chicago. Between late 1872 and early 1873, she was lengthened by 30 feet (9.1 m), and had her passenger cabins removed. Also in 1873, Merchant was sold to the Erie & Western Transportation Company (also known as the "Anchor Line") of Erie, Pennsylvania.
