Slapout is an unincorporated hamlet in Beaver County, Oklahoma, United States.

It sits on the northwest corner of the land Johnson had acquired with a government claim in 1904, three years before Oklahoma became a state.

At one time, the town had 10 inhabitants and included the Hagan Grocery on the south side of the highway.

Today, the gas station in the town is a regular stop for Tulsa and Oklahoma City residents traveling to Colorado.

The town was featured in a newspaper photo essay by Robert R. Mercer in the Tulsa Tribune in the 1970s.
