The University of Louisville Louis D. Brandeis School of Law, commonly referred to as The University of Louisville School of Law or the Brandeis School of Law, is the law school of the University of Louisville. Established in 1846, it is the oldest law school in Kentucky and the fifth oldest in the country in continuous operation. The law school is named after Justice Louis Dembitz Brandeis, who served on the Supreme Court of the United States and was the school's patron. Following the example of Brandeis, who eventually stopped accepting payment for "public interest" cases, Louis D. Brandeis School of Law was one of the first law schools in the nation to require students to complete public service before graduation.

The school offers six dual-degree programs that allow students to earn an MBA, MSW, MA in humanities, M.Div. (with the Louisville Presbyterian Theological Seminary), MA in political science, and MUP in urban planning while attaining their J.D. These classes are offered in conjunction with other University of Louisville departments.

The school's law library contains 400,000 volumes as well as the papers of Louis D. Brandeis and John Marshall Harlan, both Supreme Court Justices and native Kentuckians. It is one of only thirteen Supreme Court repositories in the nation. The law school's flagship law review is the University of Louisville Law Review.

According to University of Louisville's 2018 ABA-required disclosures, 92% of the Class of 2018 was employed within ten months of graduation. This includes 76% who obtained full-time, long-term, JD-required employment ten months after graduation, excluding solo practitioners.

Louis D. Brandeis School of Law began in 1846 as the Law Department of the University of Louisville. For most of the nineteenth century the Law Department remained small and focused on practical education. "As late as the 1870s the school still supported a faculty of only three professors, each of whom met classes two days per week for four hours." Classes were held in the late afternoon to allow students to keep daytime jobs as law clerks. The faculty ignored the casebook method of instruction that was being developed at Harvard Law School at the time, instead encouraging students to visit local courts and offering optional mock court sessions. The "school literature even boasted that the faculty consisted of 'practical lawyers' and not professional educators." As a result, prominent faculty members such as James Speed and Peter B. Muir often eschewed their part-time positions in favor of politics or private practice.

The turn of the twentieth century saw the Law Department finally begin to accept emerging national standards in legal education. In 1909, the school adopted Harvard Law's casebook method. In 1911, the school graduated its first female student, N. Almee Courtright. In 1923, the Law Department officially became the School of Law and hired a full-time professor. The following year University of Louisville President Arthur Younger Ford insisted that students must take some college courses before being admitted to the law school.

Despite these efforts at reform, the students and professors of the School of Law continued to prefer part-time practical education over the national trend towards more formal legal education. This partly reflected the success of and competition from the Jefferson School of Law, which opened in 1905 and offered night classes.^{[citation needed]}

Organized by several prominent local attorneys, the part-time professors at the Jefferson School of Law received tuition directly from the students and were responsible for renting classroom space. With students wishing to clerk and part-time professors continuing to practice, both schools were located within walking distance of the courthouse. As the national trend continued towards formal legal education, the Jefferson School of Law found it difficult to manage as a part-time law school. In 1950 the Jefferson School of Law merged with the University of Louisville School of Law.
