Adamson is a ghost town in Pittsburg County, Oklahoma, United States. Comprising 4 square miles, it was located between McAlester and Wilburton. The town contained 15 coal mines. Four mines were major producers. A post office was established at Adamson, Indian Territory on March 1, 1906. The town was named for Peter Adamson, a mine owner. It was a prosperous coal mining town before and during World War I, especially during 1913 to 1919. On September 4, 1914, Adamson was the site of one of the worst coal mine disasters in the United States. The town never recovered economically, and is now considered a ghost town. It has since been largely engulfed by Eufaula Lake.
