Crescent is a city in Logan County, Oklahoma, United States.

Crescent was formed with the Indian Appropriations Act of 1889 on March 2, 1889, and officially started that fall when William Brown began selling general merchandise out of a wagon.

A post office christened "Crescent City" was established on February 21, 1890, the name taken from a moon-shaped glade where the town began.

The Denver, Enid and Gulf Railroad laid track one mile (1.6 km) west of the city in 1902, and the city obtained 160 acres (0.65 km2) of land from two farmers (C. E. Wells and J. H. Rhoades) creating "new Crescent" or "West Crescent"; eventually the town moved to the new location.

[5][7] The site became the center of highly controversial revelations within the petrochemical industry, when in the early 1970s, working conditions and manufacturing practices at the facility became dangerous.

[8] The United States Environmental Protection Agency (EPA) stated that the groundwater contamination (near where the company once buried radioactive waste) was rising near the plant and was 400 times higher than federal drinking-water standards allowed in 1989, while levels were 208 to 360 times higher than federal standards in 1985–87.
