Soap Creek is a stream in Morgan County in the U.S. state of Missouri. It is a tributary to the Lake of the Ozarks.
The stream headwaters arise at 38.2692°N -92.9025°W and it flows generally east to its confluence with the waters of Lake of the Ozarks at 38.2739°N -92.8122°W. The source area lies just east of Missouri Route 135 and it passes under Missouri Route 5 approximately three miles south of Gravois Mills, Missouri just before entering the Lake.[1] Prior to flooding of the lake the stream entered Gravois Creek about 2.5 miles further east.[2]
Soap Creek was so named on account of deposits of soapstone in the area.[3]
