Crooked Creek is a stream in Andrew County in the U.S. state of Missouri. It is a tributary of the Platte River and is long.
The stream begins in eastern Platte Township, northeast of Whitesville and travels a southwesterly course for its entire length. It crosses Route 48 about halfway along its length, and flows into the Platte River in central Empire Prairie Township east of Happy Holler Conservation Area.
The former hamlet of Flag Springs was settled along the southeastern bank of the stream.
