James C. Carpenter was a Lancaster County, Pennsylvania covered bridge builder. He is known to have built nine covered bridges, five of which still exist. Two of his bridges, Herr's Mill Covered Bridge and Colemanville Covered Bridge, are among the longest covered bridges remaining in the county. Only Elias McMellen is known to have built more covered bridges in the county, including a rebuild of Kauffman's Distillery Covered Bridge and Leaman's Place Covered Bridge, both originally built by James C. Carpenter.
