Chaonia is an extinct town in Wayne County, in the U.S. state of Missouri.[1] The site was on the bank of the St. Francis River and is now within Lake Wappapello. The Chaonia Landing recreation area at the end of Missouri Route W is about one-half mile south of the original location. The Chaonia Cemetery is on a ridge one half mile east of the recreation area.[2]
Chaonia was originally called Wellsdale, and under the latter name was platted in 1887 when the railroad was built to that point.[3] A post office called Chaonia was established in 1888, and remained in operation until 1940.[4]
