Martins Creek is a 10.4-mile-long (16.7 km)[1] tributary of the Delaware River in eastern Pennsylvania in the United States.[2] In all, the main creek and its two branches drain an area of 46.7 square miles.[3] Martins Creek joins the Delaware just south of the town of Martins Creek.[2]
The stream was originally referred to as Tunam's or Turnami Creek, probably of Native American origin. It was known as Martin's Creek as early as 1805, named for James Martin, an early settler to the town Martins Creek, who built a grist mill here around 1747 and later served as a colonel during the Revolutionary War.[3]
