Marcus Servilius Pulex Geminus was a Roman statesman during the Second Punic War, and the early decades of the second century BC.
The Servilii Gemini were a branch of an old and distinguished patrician family, but either Gaius or his sons went over to the plebeians, for reasons that are not entirely clear.
Servilius' elder brother, Gaius, was tribune of the plebs in 211 BC, consul in 203, and dictator in 202.
Servilius' additional surname, Pulex, refers to a flea, but the circumstances of this cognomen are not mentioned in any source.
The Vatiae, a plebeian family of the Servilii, including several of the moneyers whose coins depict Marcus Servilius Pulex Geminus, are thought to be descended through this line.
