The University of Alabama (informally known as Alabama, UA, or Bama) is a public research university in Tuscaloosa, Alabama. Established in 1820 and opened to students in 1831, the University of Alabama is the oldest and largest of the public universities in Alabama as well as the University of Alabama System. It is classified among "R1: Doctoral Universities – Very high research activity".

The university offers programs of study in 13 academic divisions leading to bachelor's, master's, education specialist, and doctoral degrees. The only publicly supported law school in the state is at UA. Other academic programs unavailable elsewhere in Alabama include doctoral programs in anthropology, communication and information sciences, metallurgical engineering, music, Romance languages, and social work.

As one of the first public universities established in the early 19th century southwestern frontier of the United States, the University of Alabama has left a cultural imprint on the state, region, and nation over the past two centuries. The school was a center of activity during the American Civil War and the Civil Rights Movement. The University of Alabama varsity football program (nicknamed the Crimson Tide), which was inaugurated in 1892, ranks as one of the ten winningest programs in US history. In a 1913 speech then-president George H. Denny extolled the university as the "capstone of the public school system in the state [of Alabama]", lending the university its current nickname, The Capstone. In addition, university alumni and faculty include 59 Goldwater Scholars, 15 Rhodes Scholars, 16 Truman Scholars, 36 Hollings Scholars, and 16 Boren Scholars.
