Publius Sittius (died 44 BC) was a Roman eques and mercenary commander. As a mercenary he was employed by king Bocchus II of East-Mauretania. Sittius fought for Bocchus against king Juba I of Numidia, capturing Juba's capital of Cirta and defeating the Numidian army under general Saburra (the victor of the Battle of the Bagradas). He also supported Julius Caesar in the civil war between Caesar and the Optimates, ultimately catching and killing Faustus Cornelius Sulla and Lucius Afranius and destroying Scipio's fleet off Hippo Regius.[1] He was a personal friend of Marcus Tullius Cicero.[2]
