The gens Mummia was a plebeian family at Rome. Members of this gens are first mentioned after the Second Punic War, and within a generation, Lucius Mummius Achaicus became the first of the family to obtain the consulship. Although they were never numerous, Mummii continued to fill the highest offices of the state through the third century AD.

The praenomina associated with the Mummii include Lucius, Quintus, Spurius, and Marcus.

As the Mummii were neither a large nor an old family, few of them are found with any surname in the time of the Republic. The chief exception was Achaicus, an agnomen won by Lucius Mummius, the consul of 146 BC, for his conquest of Greece, and he is said to have been the first novus homo to have earned such a distinction through his military achievements.^[1] Members of this gens are frequently found with cognomina in imperial times.

This list includes abbreviated praenomina. For an explanation of this practice, see filiation.
