Marilyn Milian (born May 1, 1961), known professionally as Judge Milian, is an American television personality, lecturer, retired Florida Circuit Court judge and court-show arbitrator. For 22 seasons from March 12, 2001 to July 21, 2023, Milian starred in the American courtroom television series The People's Court, replacing Jerry Sheindlin. Justice for the People with Judge Milian, where Milian hears cases presented by actors improvising as litigants, premiered in autumn 2023.

Milian is the first Hispanic arbitrator to preside over a court show and during The People's Court's 2001–2023 season she became the show's longest-serving judge, surpassing Joseph Wapner, the show's inaugural jurist. She is also the most decorated TV judge, with 16 Daytime Emmy nominations and five wins in the Outstanding Legal/Courtroom Program for The People's Court.

Milian was born in Manhattan to Cuban parents Jorge, a general contractor, and Georgina Milian. She spoke Spanish before learning English and is fluent in both languages. The family moved from Astoria, Queens, to Miami when she was eight years old. She graduated from St. Brendan High School.

Milian earned her undergraduate degree in psychology from the University of Miami. She then attended Georgetown University Law Center, earning her J.D. She spent a year working at Harvard Law School, where she served as director of training for the Guatemala Project. She was responsible for training the Guatemalan trial judiciary, defense, and prosecution bar in investigatory and trial techniques.

Milian was appointed assistant state attorney for the Dade County State Attorney's Office by Janet Reno, who was then the county's state attorney. After ten years in that position, she then worked for the Miami County Court, serving in the domestic violence, criminal, and civil divisions. In 1999, Florida governor Jeb Bush appointed Milian to the Miami Circuit Court, where she served in the Criminal Division. In 2001, she replaced Jerry Sheindlin as judge of The People's Court, and became the first Hispanic judge on any English-language television court show. Milian has listed as an adjunct faculty member of the University of Miami School of Law, teaching litigation skills.

Milian served as presiding judge in the second life of the courtroom show The People's Court, the first arbitration-based reality court show and the second-longest running court show in history. Milian presided over the program from the spring of 2001, which was late in The People's Court's 17th season (or the fourth season of the revived version of the show), to the end of the 2022-23 season.

The People's Court has featured several arbitrators, with Milian currently holding the title of the longest-presiding arbitrator over the series. By the completion of the show's 28th season (2012–13), Milian had completed twelve and a half seasons presiding over the program, officially making her the longest-running judge on The People's Court. The late Joseph Wapner, the show's original judge, was the previous holder of this record. By the spring of 2021, she reached 20 years as presiding judge over the program.

In contrast to The People's Court's previous arbiters, Milian is considerably more animated in her role, but she's also known for being levelheaded and logical in her observations and handling of the cases. Although engaging for the most part, Milian also dishes out a good-natured, lively sass at the litigants and does not tolerate any disrespect from them.
