Lutatius was the name of an ancient Roman family (gens). They rose into prominence during the First Punic War and produced several consuls during the subsequent generations, but were not one of the gentes maiores. The Lutatii were noble plebeians.
Due to the ancient Roman custom of naming children after their famous ancestors, several important Lutatii had the same name. The common cognomen in the family is Catulus, meaning "puppy". "Catulus" may be etymologically related to, but should not be confused with, the name Catullus.
Gaius Lutatius Catulus (consul of 242 BC)
Gaius Lutatius Catulus was the first consul of the family (a novus homo), elected in 242 BC. He was the hero of the Battle of Aegates Islands that ended the First Punic War by defeating Hanno the Great of Carthage.

Quintus Lutatius Catulus (consul of 78 BC)
Son of the above, a consul of 78 BC with Marcus Aemilius Lepidus and censor in 65 BC ; his mother was Servilia. He was one of the very few consulares who survived the civil wars and the purges of Sulla. Therefore he became a very influential person in the Senate. He was married to a Hortensia (sister of Quintus Hortensius, the orator). His sister, Lutatia, in turn was married to his wife's brother Quintus Hortensius, and was the mother of his children, including Hortensia. He was a part of the "boni" faction of the senate and died in the year 61 BC.
