Pomponius Bassus (175 – 221) was a Roman senator active during the reigns of Septimius Severus, Caracalla, and Geta.
Between 212 and 217 Bassus served as a legatus of Inferior or Superior Moesia and possibly as Roman governor of Mysia.
Before June 221, Emperor Elagabalus became attracted to Faustina's charm, beauty, and imperial descent.
After Bassus' execution, Elagabalus forbade Faustina to mourn him.
In July 221, Elagabalus took Faustina as his third wife, but he divorced her by the end of the year.
