Quintus Mucius Scaevola Pontifex (died 82 BCE), the son of Publius Mucius Scaevola (consul in 133 BCE and also Pontifex Maximus) is a politician of the Roman Republic and an important early authority on Roman law.

He is credited with founding the study of law as a systematic discipline.

He is nephew and son of two men elected Pontifices Maximi, and is himself elected chief priest of Rome.

He is probably also the first Roman Pontifex Maximus to be murdered publicly, in Rome in the very Temple of the Vestals, signifying a breakdown of historical norms and religious taboos in the Republic.
