Pontius Aquila (possibly Lucius Pontius; died 21 April 43 BC) was a Roman politician, military commander, and one of the assassins of Julius Caesar. In 45 BC, as tribune of the plebs, he annoyed Caesar by refusing to stand during his triumphal procession, and, in the following year, joined in the conspiracy to kill the dictator. Aquila died fighting at the Battle of Mutina against Marc Antony in April 43 BC, before the formation of the Second Triumvirate later that year.
