The Paul M. Hebert Law Center, often styled "LSU Law", is a public law school in Baton Rouge, Louisiana. It is part of the Louisiana State University System and located on the main campus of Louisiana State University. Because Louisiana is a civil law state, unlike its 49 common law sister states, the curriculum includes both civil law and common law courses, requiring 94 hours for graduation, the most in the United States. In the Fall of 2002, the LSU Law Center became the sole United States law school, and only one of two law schools in the Western Hemisphere, offering a course of study leading to the simultaneous conferring of a J.D. (Juris Doctor), which is the normal first degree in American law schools, and a D.C.L. (Diploma in Comparative Law), which recognizes the training its students receive in both the common and the civil law. Until voting in April 2015 to realign itself as an academic unit of Louisiana State University, the Paul M. Hebert Law Center was an autonomous school. Its designation as a Law Center, rather than Law School, derives not only from its formerly independent campus status but also from the centralization on its campus of J.D. and post-J.D. programs, foreign and graduate programs, including European programs at the Jean Moulin University Lyon 3 School of Law, France, and the University of Louvain, Belgium, and the direction of the Louisiana Law Institute and the Louisiana Judicial College, among other initiatives. According to the school's 2017 ABA-required disclosures, 81.3% of the Class of 2017 obtained full-time, long-term, bar passage-required employment nine months after graduation, excluding solo practitioners.

The field house is considered the original student union and included a post office, ballroom, gymnasium and also featured the largest swimming pool in the United States at the time.The field house was home to the LSU Tigers and LSU Lady Tigers swimming and diving teams until the LSU Natatorium was built in 1985.

KLSU (91.1 FM) is the student-run college radio station for Louisiana State University in Baton Rouge, Louisiana with a radio format of variety music and specialty programming. The radio station is part of the university's Student Media Program and employs students as DJs and management staff. KLSU broadcasts across the Baton Rouge area at 23,000 watts of power, and is able to reach up to 40 miles (64 km) beyond the LSU campus. The station is licensed under the Federal Communications Commission (FCC) as a non-commercial educational (NCE) radio station. KLSU is one of 700 college radio stations across the United States that submits music chart reports to the weekly publication College Music Journal magazine. KLSU is unusual in that its callsign begins with a K but is located on the east side on the Mississippi River (which should have it beginning with a W), and the callsign was not the beneficiary of the FCC grandfather clause. During the application period for the station, it was discovered that the desired callsign, WLSU, was already held by the University of Wisconsin–La Crosse. Because KLSU would be located within a mile of the Mississippi River, the FCC granted an exemption to the K–W rule so it could have LSU in its callsign. In April 2016, KLSU significantly upgraded their power from 5,700 watts class A to 23,000 watts class C3.
