The Pittsburgh Commercial was a morning daily newspaper published from 7 September 1863 to 14 February 1877 in Pittsburgh, Pennsylvania. It was outspokenly Republican in its political commentary. Chief editors included Thomas J. Bigham, Charles D. Brigham, and Russell Errett; poet Richard Realf was an assistant editor. The owners of the competing Pittsburgh Gazette eventually purchased the Commercial and consolidated the two papers as the Pittsburgh Commercial Gazette.
