Lucerius (died 740) was the third Abbot of Farfa, succeeding Aunepert in 724 at the latest.
In his first year, he received a grant of a church with its (unspecified) lands from Duke Thrasimund II of Spoleto.
[1] This church, dedicated to Saint Getulius, lay within the jurisdiction of the Diocese of Rieti, and according to the tenth-century Exceptio Relationum Thrasimund had to compensate the bishop for his loss.
[2] In 739 Lucerius received a privilege from King Liutprand confirming its possessions and granting it the freedom to elect its own abbots.
Liutprand marched an army into central Italy, forcing Thrasimund to flee to Rome and installing Hilderic as duke in Spoleto.
