Olathia is a community in north-central Douglas County, Missouri United States. It is located approximately six miles southeast of Mansfield along Missouri Route U and is nine miles northeast of Ava. It is on a ridge between Puncheon Camp Creek one-half mile to the northeast and Bryant Creek one and a quarter mile to the southwest.[1]
