Lucius Vibullius Rufus, sometimes known as Lucius Vibullius Hipparchus, was a Greek aristocrat who lived in the 2nd century AD in the Roman Empire.
Rufus was a member of a very wealthy and prominent Athenian family. He was the son of Publius Aelius Vibullius Rufus, who served as an Archon of Athens in 143-144 and his unnamed wife. His paternal grandfather was Lucius Vibullius Hipparchus, who served as an Archon of Athens in 118-9. His father was first cousin with the prominent Greek sophist Herodes Atticus.
Rufus was married before 160 and had at least one son, Lucius Vibullius, whom Herodes Atticus adopted as his son sometime after 160, and became known as Lucius Vibullius Claudius Herodes. Herodes Atticus with his wife, Aspasia Annia Regilla, had betrothed their second daughter Athenais to Rufus, although they were paternal second cousins.
In 160 Rufus married Athenais as his second wife, while this was Athenais’ first marriage. In the next year, Athenais bore Rufus a son, Lucius Vibullius Hipparchus, but died shortly after.
