East Duke, now known as Duke, is a town in Jackson County, Oklahoma, United States. The population was 394 as of the 2020 United States census. It is located about 14 miles west of the county seat of Altus, and is located at the intersection of US Route 62 and Oklahoma State Highway 34.

The town of Duke was founded in 1890. Speculation about the location of a projected railroad sparked a separation in the community, creating an old town called West Duke, and a new town called East Duke. While the community reconciled in 1915 when the parties eventually buried a hatchet delivered in a horse-drawn hearse, West Duke did not ultimately survive, and East Duke is now known simply as Duke.

According to the United States Census Bureau, the town has a total area of 0.4 square miles (1.0 km), all land.
