Moyamensing was originally a township on the fast land of the Neck, lying between Passyunk and Wicaco. It was incorporated into the Philadelphia County, Pennsylvania and is today primarily a neighborhood in the South Philadelphia section of Philadelphia, Pennsylvania, United States.
The tract was granted by the Dutch West India Company Lieutenant Alexander d'Hinoyossa, Vice-Director of New Amstel to Martin Clensmith, William Stille and Lawrence Andries. In 1684, when the land was turned over from the Dutch to the English, the title was given by William Penn to William Stille, Lassey Andrews, Andrew Bankson and John Matson.
Moyamensing Township included this ground and Wicaco, except such parts of the latter as were included in Southwark. Its northern boundary was South Street and below the existing parts of Southwark; its eastern boundary was the Delaware River, and its western boundary was Schuylkill Sixth (Seventeenth Street). 
In 1816 the greatest length of Moyamensing was estimated to be 3 miles; the greatest breadth, 2 miles; area, 2,560 acres (10 km²). By act of March 24, 1812, the inhabitants of Moyamensing were incorporated by the style of "the commissioners and inhabitants of the township of Moyamensing." By act of April 4, 1831, the township was divided into East and West Moyamensing. The township was one of the earliest created after the settlement of Pennsylvania, and became part of Philadelphia in 1854.
