Lucius Coelius Festus was a Roman senator, who was appointed to several praetorian offices during the reign of Antoninus Pius.
Festus was originally of the equestrian class, but apparently was adlected into the Senate inter tribunicos at the end of the reign of Hadrian.
The praetorian portion of his cursus honorum is recorded on an inscription erected at Veleia by the city council to celebrate his patronage.
[3] After achieving the praetorship, Festus was appointed prefectus frumenti dandi ex Senatus consultum.
Géza Alföldy notes he was one of three men who held this position in a narrow period: Alföldy arranges the three putting Lucius Novius Crispinus (later suffect consul around 150) first, then was replaced by Festus around the year 138, and three years later was in turn replaced by Quintus Fuficius Cornutus (later suffect consul in 147).
