Lucius Minucius Basilus (died summer 43 BC) was a military commander and politician of the late Roman Republic, a trusted associate of Julius Caesar, who later participated in Caesar's assassination.
It was to Basilus that Cicero wrote his first excited note after hearing of the assassination of Caesar.
He was, however, mortally offended because Caesar would not give him a province after his praetorship in 45 BC, but only a sum of money in return for his services, and so joined the conspiracy against him.
Basilus, denied a provincial command despite being a praetor, was insulted that Caesar tried to placate him with money, causing him to join the conspiracy.
He should probably be distinguished from L. Minucius Basilus, who took the name (instead of M. Satrius) on his adoption by a rich uncle, [and] mentioned as assuming by force the position of patronus over certain towns in Italy.
