Turtle Creek is a borough in Allegheny County, Pennsylvania, 12 miles (19 km) southeast of Pittsburgh. The population was 5,349 at the 2010 census. George Westinghouse gave life to the place by constructing a manufacturing plant nearby. Turtle Creek takes its name from a small stream that flows into the Monongahela River. Before white settlers arrived, there was a small village of Native Americans living there from the Turtle Clan of the Iroquois Nation.
