Gaius Valerius Triarius (died c. 45 BC[citation needed]) was a First Century BC Roman politician and general, a member of the gens Valeria. During the Third Mithridatic War he served as a legate to Lucius Licinius Lucullus, the Roman commander in charge of the war effort against king Mithridates VI of Pontus. He played a pivotal role in the capture of Heraclea Pontica, but was later defeated by Mithridates at the Battle of Zela in 67 BC.
