Northwestern Oklahoma State University, also known as NWOSU, is a university in Alva, Oklahoma, United States, with satellite campuses in Enid and Woodward. A state university, it offers both bachelor's and master's degrees.

In 1897, a normal school, or school for teachers, was established in Alva by an act of the Oklahoma Territorial Legislature. It was the second normal school in Oklahoma, charged with preparing teachers to serve the many one-room schoolhouses that covered the prairie. It was called the Northwestern Territorial Normal School. The new school's faculty consisted of the school's first president, James E. Ament, and two teachers. Classes were held in the Congregational Church until construction of the first building, the "Castle on the Hill," was complete in Sept.20, 1897.

The school became a four-year teachers college in 1919 and changed its name to Northwestern Oklahoma Teachers College. The school expanded in 1939 to include degrees in liberal arts as well as education, and its name changed again, to Northwestern State College. The final name change occurred in 1974 when the school was given its present name.

Northwestern Oklahoma is the geographical region of the state of Oklahoma which includes the Oklahoma Panhandle and a majority of the Cherokee Outlet, stretching to an eastern extent along Interstate 35, and its southern extent along the Canadian River to Noble County. Northwest Oklahoma is also known by its Oklahoma Department of Tourism designation, Red Carpet Country, which is named after the region's red soil and alludes to the metaphor that the panhandle is a "red carpet" into Oklahoma. The region consists of Cimarron, Texas, Beaver, Harper, Woods, Alfalfa, Grant, Kay, Ellis, Woodward, Major, Garfield, Noble, Dewey, Blaine, Kingfisher counties.

The area is anchored economically by Enid, which also contains the region's largest commercial airport. Other important cities include Guymon, Ponca City, Woodward, and Alva.

Generally dry and flat, Northwest Oklahoma also contains a decent allotment of mountain ranges and mesas, a testament to the Southwest Tablelands ecoregion that dominates the area. Canyons and grasslands, such as the Rita Blanca National Grassland, help to give Northwest Oklahoma a distinctive Southwest-like landscape, differing from most of the state. Black Mesa, the state's highest peak, is part of a large range of mesas in the panhandle which stretch into New Mexico. Another mesa range, the Glass (or Gloss) Mountains, sits in the center of Northwest Oklahoma, just south of the Cimarron River along Highway 412. Great Salt Plains Lake, one of the largest inland salt lakes in the United States, is located near Alva.

Oklahoma (ⁱ/ˌoʊkləˈhoʊmə/) (Pawnee: Uukuhuúwa , Cayuga: Gahnawiyoˀgeh ) is a state located in the South Central region of the United States of America. Oklahoma is the 20th most extensive and the 28th most populous of the 50 United States. The state's name is derived from the Choctaw words okla and humma, meaning "red people", and it is known informally by its nickname, The Sooner State. Formed by the combination of Oklahoma Territory and Indian Territory on November 16, 1907, Oklahoma was the 46th state to enter the union. Its residents are known as Oklahomans or, informally "Okies", and its capital and largest city is Oklahoma City.

A major producer of natural gas, oil, and agriculture, Oklahoma relies on an economic base of aviation, energy, telecommunications, and biotechnology. It has one of the fastest growing economies in the nation, ranking among the top states in per capita income growth and gross domestic product growth. Oklahoma City and Tulsa serve as Oklahoma's primary economic anchors, with nearly 60 percent of Oklahomans living in their metropolitan statistical areas.

A state university system in the United States is a group of public universities supported by an individual state, or a similar entity such as the District of Columbia. These systems constitute the majority of public-funded universities in the country. Each state supports at least one such system.

Federal funded colleges and universities are limited to military personnel and government employees. Members of foreign militaries and governments also attend some schools. These schools include the United States military academies, Naval Postgraduate School, and military staff colleges.

A state university system normally means a single legal entity and administration, but may consist of several institutions, each with its own identity as a university. Some states—such as California and Texas—support more than one such system.

State universities get subsidies from their states. The amount of the subsidy varies from university to university and state to state, but the effect is to lower tuition costs below that of private universities. As more and more Americans attend college, and private tuition rates increase well beyond the rate of inflation, admission to state universities is becoming more and more competitive.
