The sestertius, or sesterce, (plural: sestertii) was an ancient Roman coin. During the Roman Republic it was a small, silver coin issued only on rare occasions. During the Roman Empire it was a large brass coin.

The sestertius was introduced ca. 211 BC as a small silver coin valued at one-quarter of a denarius. In 23 BC, with the coinage reform of Augustus, the denomination of sestertius was introduced as the large brass denomination.
