Porum is a town in Muskogee County, Oklahoma, United States. It was named for John Porum Davis, a rancher, Civil War veteran, and Cherokee Nation councilman from the Canadian District in Indian Territory. The community was first known as Porum Gap, which united with another village named Starvilla in 1905. The product of this union became the present town of Porum. The population was 727 at the 2010 census, an 0.3 percent increase from 725 at the 2000 census.
The area is rich in history, including that of the Starr clan who were of the Cherokee "Treaty faction" and became immersed in troubles during the early turbulent days of the Cherokee Nation. They were attacked by, and counterattacked, men of the Ross faction. Tom Starr was alleged to have killed 100 men in his time, although the figure may be exaggerated. Tom was a half-blood, Irish and Cherokee, and had five sons, one of whom was Sam who became the husband of Belle Starr, forever linked with the history of Porum. In later years, Pony Starr who lived on the edge of Porum was involved in the Porum Range War and was regarded as the straightest shot and most fearless man of his clan.
A post office was established in Porum Gap March 25, 1890.
