Grayson is a village[2] in Clinton County, in the U.S. state of Missouri. It was listed as a census-designated place (CDP) in the 2020 census.
The community is on US Route 169 four miles north of Trimble and approximately six miles west-southwest of Plattsburg. The Smithville Reservoir on the Little Platte River is about 3.5 miles to the east.[3]
Grayson was platted in 1871, and named after the maiden name of the wife of the original owner of the town site.[4] A variant name was Graysonville. A post office called Graysonville was established in 1871, the name was changed to Grayson in 1882, and the post office closed in 1954.[5]
