Turtle Creek is a 21.1-mile-long (34.0 km)[2] tributary of the Monongahela River that is located in Allegheny and Westmoreland counties in the U.S. state of Pennsylvania.[3] Situated at its juncture with the Monongahela is Braddock, Pennsylvania, where the Battle of the Monongahela ("Braddock's Defeat") was fought in 1755.
During the mid-nineteenth century, the Pennsylvania Railroad laid tracks along the stream as part of its Main Line from Philadelphia to Pittsburgh.
