Manayunk () is a neighborhood in the section of Lower Northwest Philadelphia in the state of Pennsylvania. Located adjacent to the neighborhoods of Roxborough and Wissahickon and also on the banks of the Schuylkill River, Manayunk contains the first canal begun in the United States (although not the first completed, due to budget problems). The area's name is derived from the language of the Lenape Indians (later called the Delaware Indians by Europeans). In 1686-dated papers between William Penn and the Lenape, the Lenape referred to the Schuylkill River as "Manaiung", their word for "river", which literally translates as "place to drink"; the word was later altered and adopted as the town's name.
