Gaius Marcius Rutilus Censorinus was a Roman politician from the plebeian gens Marcia in the fourth and third centuries BC.
His father Gaius Marcius Rutilus served as consul four times in the years 357 - 342 BC.
Marcius served as tribune of the people in 311 BC.
In that year, he fought against the Samnites and conquered Alifae in Campania, but was seriously wounded in a subsequent battle.
He is said to have brought forward a law precluding anyone from holding the censorship more than twice in the future.
