Faustus Cornelius Sulla Felix (22 – 62 AD) was one of the lesser known figures of the Julio-Claudian dynasty of ancient Rome.
In 47 the emperor Claudius, who was his mother's cousin, arranged for Felix to marry his daughter, Claudia Antonia.
In 58 another imperial freedman falsely accused Felix of plotting to attack Nero, possibly at the latter's instigation.
Nero treated Felix as proven guilty, had him exiled in 59 and confined to Massilia (modern Marseille, France).
Felix was murdered at dinner, five days after Tigellinus gave his orders, and his head transported to the palace.
