Lucius Cassius Longinus Ravilla was a Roman politician. He served as consul in 127 BC and censor at the following lustrum in 125 BC. His first recorded office was that of tribune of the plebs in 137 BC. As a tribune of the plebs, he successfully proposed in the concilium plebis a law to introduce secret ballot for all trials before the Assemblies except those related to perduellio (treason); the bill was supported by Scipio Aemilianus but opposed by the then-consul Marcus Aemilius Lepidus Porcina and his tribunician colleague Marcus Antius Briso.
