The Cincinnati Porkers was a professional baseball team from Cincinnati, Ohio. The team was named for Cincinnati's important role in the pork-processing industry during the nineteenth century. The squad's manager was Michael Joseph Kelly, and the club was also known as the Cincinnati Kelly's Killers. The team existed only for the 1891 season. The Porkers won forty-three games and lost fifty-seven, finishing seventh in the American Association, a professional league that lasted from 1882 to 1891. At least twenty-five different teams played in this league over the course of the American Association's existence. The Cincinnati Porkers ceased to exist with the end of the American Association after the 1891 season.
