Lucius Cornelius Merula (died 87 BC) was a politician and priest of the late Roman Republic.
Lucius Cornelius Merula held the office of flamen Dialis (high priest of Jupiter), and wore the flamen's cap at all times, unlike the other flamines who only wore it while performing sacrifices.
He negotiated the return of Cinna and Marius from banishment, and abdicated his consulship.
However, false charges were made against him during Marius's purges of his political enemies, and he committed suicide, opening his veins in the Temple of Jupiter Capitolinus and imploring the gods to avenge him on Cinna and his allies.
[1] Scholars disagree but this nomination was annulled by Sulla subsequently.
