Lucius Julius Caesar (consul 64 BCE) (died after 43 BCE) is a consul of 64 BCE.

During the debate in the senate with regards to the punishment of the Catalinarian conspirators, he votes for the death penalty although his own brother-in-law Publius Cornelius Lentulus (Sura) is among them.

He is a legate in Gaul in 52 BCE and a high priest.

After the conquest of Gaul he moves against Pompey.

He accompanies Julius Caesar into civil war.

After Caesar's assassination he allies with his nephew Mark Antony.

He and his nephew fall out in 43 BCE, and he is proscribed by Mark Antony but the pleas of his sister save him from the death penalty.
