Breakneck Creek is a tributary of Connoquenessing Creek that flows in a northwardly direction in Western Pennsylvania. It forms in the village of Bakerstown in Allegheny County then flows northwest through the borough of Valencia in Butler County.
From there, it continues northwest through the boroughs of Mars, Callery, and Evans City. Breakneck flows a few more miles until it reaches the village of Eidenau where it flows into Connoquenessing Creek.
