The University of Nebraska–Lincoln (Nebraska, NU, or UNL) is a public land-grant research university in Lincoln, Nebraska, United States. Chartered in 1869 by the Nebraska Legislature as part of the Morrill Act of 1862, the school was 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 is organized into nine colleges and offers over two hundred degree programs 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.

Nebraska is classified among "R1: Doctoral Universities – Very high research activity". 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 in 2021 was 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."
