Mario Victor "Marvic" Famorca Leonen (born December 29, 1962) is a Filipino jurist who has served as an associate Justice of the Supreme Court of the Philippines since 2012. President Benigno Aquino III appointed Leonen to the position at the age of 49, making him the second-youngest jurist in the court's history. Following the retirement of Estela Perlas-Bernabe in 2022, he has been the senior associate justice of the court.
Before joining the Supreme Court, he served as the chief peace negotiator for the Republic of the Philippines in peace talks with the Moro Islamic Liberation Front. Leonen is sometimes referred to as "The Great Dissenter" for his liberal and human rights-oriented decisions, which often contrast with those of more conservative justices aligned with Rodrigo Duterte.
Leonen has served as dean of the University of the Philippines College of Law from 2008 to 2011. He is known for his work in environmental activism and community organizing.
