The University of Nebraska–Lincoln (Nebraska, NU, or UNL) is a public land-grant research university in Lincoln, Nebraska. Chartered in 1869 by the Nebraska Legislature as part of the Morrill Act of 1862, the school was known as the University of Nebraska until 1968, when it absorbed the Municipal University of Omaha to form the University of Nebraska system. It is the state's oldest university and the flagship institution of the state-wide system. The university has been governed by the Board of Regents since 1871, whose members are elected by district to six-year terms.

The university is organized into nine colleges: Agricultural Sciences and Natural Resources, Architecture, Arts and Sciences, Business, Education and Human Sciences, Engineering, Fine and Performing Arts, Journalism and Mass Communications, and Law. NU offers over two hundred degrees across its undergraduate, graduate, and doctoral programs. The school also offers programs through the University of Nebraska Omaha College of Public Affairs and Community Service, the University of Nebraska Medical Center College of Dentistry and College of Nursing, and the Peter Kiewit Institute, which is managed in partnership with the Kiewit Corporation. Among approximately 300,000 Nebraska alumni are three Nobel laureates, four Pulitzer Prize winners, one Turing Award winner, and twenty-two Rhodes Scholars.

Nebraska is considered to have "very high research activity" based on the Carnegie Classification. According to the National Science Foundation, Nebraska spent $320 million on research and development in 2020. Between its three campus locations (City Campus, East Campus, and Nebraska Innovation Campus) the university has over one hundred classroom buildings and research facilities. The university's enrollment is 19,552 undergraduate students and 4,879 graduate students, with 1,595 full-time or part-time instructional faculty. Undergraduate admission to the school is considered "more selective."

Nebraska's athletic programs, known as the Cornhuskers, compete in NCAA Division I and are a member of the Big Ten Conference. NU's football team has won forty-six conference championships and claims five national championships, with an additional nine unclaimed. Twenty-five former Cornhuskers have been inducted into the College Football Hall of Fame. A total of 111 former Nebraska student-athletes have combined to win fifty-four Olympic medals, including sixteen gold medals.
