Lucius Quinctius Cincinnatus (519 BC – 438 BC) was an aristocrat and political figure of the Roman Republic, serving as consul in 460 BC and Roman dictator in 458 BC and 439 BC.

Cincinnatus was regarded by the Romans, especially the aristocratic patrician class, as one of the heroes of early Rome and as a model of Roman virtue and simplicity. A persistent opponent of the plebeians, when his son was convicted in absentia and condemned to death, Cincinnatus was forced to live in humble circumstances, working on his own small farm, until an invasion caused him to be called to serve Rome as dictator, an office which he immediately resigned after completing his task of defeating the rivaling tribes of the Aequians, Sabinians and Volscians.

His abandoning of his work to serve Rome, and especially his immediate resignation of his absolute authority with the end of the crisis, has often been cited as an example of outstanding leadership, service to the greater good, civic virtue, and modesty. As a result, he has inspired a number of organizations and other entities, a number of which are named for him.
