The gens Pomptina was a minor plebeian family at ancient Rome.
The gens is best known from Gaius Pomptinus, praetor in 63 BC, who helped suppress the conspiracy of Catiline, and later defeated the Allobroges.
[1] The nomen Pomptinus seems to be derived from the region of the Pomptine Marshes, in southeastern Latium.
This area was brought under Roman control following the defeat of the Volscians in 358 BC, and the tribus Pomptina organized.
In different sources, the nomen can be found as Pomptinius, Pontinius, and Pomtinus.
