Cedar Creek is a stream in Boone and Callaway counties of the U.S. state of Missouri.
The headwaters of Cedar Creek are in the northeast of Boone County about five miles east of Hallsville and one mile west of the Audrain-Boone county line.
The stream crosses under Interstate 70 about eight miles east of Columbia and enters the Mark Twain National Forest.
The stream flows east for about one mile then turns south and flows under U. S. Route 63 and into the Missouri River four miles northwest of Cedar City and across the river from Jefferson City.
The Katy Trail crosses Cedar Creek just north of its confluence with the Missouri.
