Aelius Decius Triccianus was a Roman usurper, who revolted against Emperor Elagabalus. He revolted against Elagabalus using troops still loyal to Macrinus, the previous emperor who Elagabalus had overthrown, and who Triccianus had served under. The revolt was put down, and he was executed. A damnatio memoriae was issued against him, making it impossible to establish the date of his rebellion or death.
