Hostus Lucretius Tricipitinus was a consul of the Roman Republic in 429 BC.
[1] Lucretius belonged to the ancient patrician Lucretia gens whose ancestors had been among the first consuls of the Republic.
[2] Diodorus Siculus has his praenomen as Opiter, while both Livy and Cassiodorus has him named Hostus.
The commission sent consisted of the consul, Sergius, and two former dictators, Quintus Servilius Priscus Structus Fidenas and Mamercus Aemilius Mamercinus.
Lucretius's role in the events remain obscure and other ancient writers do not comment on the actions of the consuls of 429 BC.
