Brokenstraw Creek is a 37.1-mile (59.7 km) tributary of the Allegheny River in Warren County, Pennsylvania in the United States.

[3] Brokenstraw Creek is made up of two smaller streams: The "Little Brokenstraw" originates south east of Panama, New York and flows south through Lottsville and Wrightsville to Pittsfield, PA.

From Pittsfield, the stream flows east through downtown Youngsville, Pennsylvania to Irvine when it meets the Allegheny River at the (old Seneca Indian village turned archaeological dig site) Buckaloons campground.

Both the big and little Brokenstraw Creeks and their tributaries boast good water quality, low levels of pollution and high dissolved oxygen content, making these streams highly sought after for fishermen, especially trout fishermen.

Many stretches of stream also hold Smallmouth bass and White suckers.
