- A Roman general, he is given the name "Coriolanus" after he leads the Roman armies to victory against the Volscian city of Corioles. Brave, fearsome in battle, and extremely honorable, he is also overly proud, immature, inflexible, and stubbornly aristocratic. These faults, combined with a fierce contempt for the lower classes of Rome, lead to his exile from his native city.
- A Roman noblewoman and the mother of Coriolanus. She is devoted to her son and delights in his military exploits, having raised him to be a warrior; he, in turn, often allows himself to be dominated by her iron will.
- A Roman nobleman, or patrician, and a friend to Coriolanus. Gifted with a clever tongue, he has a reputation as a great wit, which he uses adeptly to avoid conflict.
