The gens Minucia was a Roman family, which flourished from the earliest days of the Republic until imperial times. The gens was apparently of patrician origin, but was better known by its plebeian branches. The first of the Minucii to hold the consulship was Marcus Minucius Augurinus, elected consul in 497 BC.
The nomen Minucius is frequently confounded with Minicius and Municius. The Minucii gave their name to the street known as the Via Minucia, the Pons Minucius, a bridge on the Via Flaminia, and a columned hall on the Campus Martius. The gate known as the Porticus Minucia was named after the consul of 110 BC.
The Minucii used the praenomina Marcus, Publius, Quintus, Lucius, Tiberius, and Gaius. At least one early Minucius bore the praenomen Spurius. Other praenomina appear rarely, and only in the final centuries of the Republic.
The oldest branch of the family, the Minucii Augurini, were originally patrician, but in 439 BC. Lucius Minucius Augurinus went over to the plebeians, and was elected tribune of the plebs. His descendants included the consul of 305 BC and several later tribunes of the plebs. The surname was derived from the position of augur, an important priest specializing in divination. The college of augurs was held in high esteem, and membership was restricted to the patricians until 300 BC.
