El Reno is a city in and county seat of Canadian County, Oklahoma, United States. As of the 2010 census, the city population was 16,729. The city was begun shortly after the 1889 land rush and named for the nearby Fort Reno. It is located in the central part of the state, approximately 25 miles (40 km) west of downtown Oklahoma City, and is part of the Oklahoma City Metropolitan Statistical Area.
The city was originally located about five miles (8 km) north of its present location, on the banks of the North Canadian river, bearing the name Reno City, which caused its mail to get mixed up with mail for Reno, Nevada. After the second time the town flooded, it was moved to its present location and changed its name to El Reno. This word is Spanish for "the reindeer".
Historic Fort Reno was built in 1874, and first commanded by General Philip Sheridan. He named it in honor of his friend, Gen. Jesse L. Reno, who was killed in the Civil War. The grounds of the old fort became home to a research laboratory for the U.S. Department of Agriculture in 1948. The laboratory studies environmentally sustainable forage and livestock production, contributing to preservation of the great plains of North America.
