Okaton is a hamlet in Jones County, South Dakota, United States. As of the 2020 census, the population was 31.[1]
Okaton had its start in 1906 by the building of the Milwaukee Railroad through that territory.[2] It had a post office, but this closed in 2013; postal service is now provided from Murdo. There was also, until recently, a "western town" tourist attraction with a petting zoo and a functioning store. The town's entire business district had been on the town road furthest from the interstate highway, which bypassed the town; but which was closest to the railroad tracks. The closure of the railroad, followed by the interstate's placement, largely accounted for the town's dwindling.
