Rogers Locomotive and Machine Works was a 19th-century manufacturer of railroad steam locomotives based in Paterson, in Passaic County, New Jersey, in the United States. It built more than six thousand steam locomotives for railroads around the world. Most railroads in 19th-century United States rostered at least one Rogers-built locomotive. The company's most famous product was a locomotive named "The General", built in December 1855, which was one of the principals of the Great Locomotive Chase of the American Civil War.
