Publius Licinius Crassus Mucianus was the son of Publius Mucius Scaevola and Licinia, the sister of Publius Licinius Crassus, consul in 171 BC. His paternal uncle, Quintus Mucius Scaevola, had been consul in 174 BC. His elder brother, Publius Mucius Scaevola, became consul in 133 BC. Thus, Crassus Mucianus was related to several consuls. His paternal grandfather, Quintus Mucius Scaevola, had been praetor in 215 BC, but had fallen ill and died before he could stand for election to the consulship.
