The town of Wann has connections to both Cherokee and Eastern Delaware origins. The town and a nearby creek were originally named Coon, after a Delaware family, when the first post office opened July 26, 1895. The town was renamed Wann on October 13, 1899, to honor a local Cherokee, Robert F. Wann. The town was a station on the stage route between Coffeyville, Kansas and Bartlesville, Indian Territory. When the Katy Railroad built its track northwest of town in 1902, the townspeople relocated to be nearer the Wann railroad station. Wann had 201 inhabitants at Oklahoma's first census in 1907. Oil was discovered in the Wann Oil Pool about this time, leading the population to grow to 286 in 1910 and 404 in 1920. The boom collapsed and so did the population. The railroad track was abandoned in the 1980s, following the demise of the Katy Railroad. Wann's economy now depends on local farming and ranching.
