Lucius Burbuleius Optatus Ligarianus

Lucius Burbuleius Optatus Ligarianus was a Roman senator of the second century, who held several offices in the emperor's service. He was suffect consul in the nundinium of May-August 135 as the colleague of Marcus Aemilius Papus. He died while governor of Syria.

An inscription in Minturnae, erected after his death and honoring him as patron of the city, records his cursus honorum. Anthony Birley notes that this inscription and his patronage of the colony both point to Ligarianus having a residence there, but as his tribe was Quirina, and the city was enrolled in the Terentina tribe, it was not his place of origin. "Although the very rare gentilicium is not found outside of Italy", concludes Birley, "he may have been a provincial."
