Okmulgee is a city in Okmulgee County, Oklahoma, United States. The population at the 2010 census was 12,321 a loss of 5.4 percent since the 2000 census figure of 13,022. It has been the capital of the Muscogee (Creek) Nation since the United States Civil War. Okmulgee means "boiling waters" in the Creek language; other translations put it as "babbling brook" or 'Effluvium'. The site was chosen because of the nearby rivers and springs. The town is notable as the seat of the Muscogee (Creek) Nation Tribal Complex.
Okmulgee was founded in 1868, when the Creek Nation began restoring order after the Civil War. In 1869, a post office (originally spelled Okmulkee) was established, with Captain Frederick B. Severs as the first postmaster. The Creeks initially built a two-story log council house to serve as their capital. This building burned in 1878 and was replaced with a stone building that stands today. The name of the post office was officially changed to the present spelling on November 15, 1883. 
The St. Louis, Oklahoma and Southern Railway (later absorbed by the Frisco railroad) arrived in 1900 and triggered a building boom. By the time of statehood in 1907, the town had 2,322 residents and had been named the seat of Okmulgee County. The present county court house was built in 1916. The discovery of oil nearby in 1907, further expanded Okmulgee, and brought several new industries to town. These included three glass factories, a bottle factory, foundry and machine shops. The population was 4,176 in the 1920 census.

Parks and Recreation 
Recreational opportunities include Okmulgee and Dripping Springs State Parks, which offer RV and camping facilities. The parks also offer swimming, fishing, and boating opportunities through the adjacent Dripping Springs Lake, which has 18 miles (29 km) of shoreline and 1,150 acres (4,700,000 m2) of water, and the separate Okmulgee Lake. The end of Okmulgee Lake features the Okmulgee Lake Spillway, which on occasions of heavy rains and high lake levels, creates an intense man-made waterfall. Near Okmulgee is the Deep Fork National Wildlife Refuge. Established in 1993, this approximately 9,000 acres (36 km2) habitat for waterfowl along the Deep Fork River features opportunities for wildlife viewing such as along the Cussetah Bottoms Boardwalk, as well as fishing and certain archery, muzzle-loading, and small-game hunting opportunities.
Native American government 
The Muscogee (Creek) Nation, one of the historical Five Civilized Tribes, is headquartered in Okmulgee. Okmulgee is also the site of the original Creek Council House. Built by the Muscogee (Creek) Nation as a capitol building in 1878, the Council House was eventually sold to the City of Okmulgee where it served various purposes over the years, including a Sheriff's office, a YMCA, and more recently, a Creek Council House Museum. The City agreed in August 2010 to resell the building to the Creek Nation, and the ceremony commemorating the repossession of the building was held in November 2010.
