The Stadium of Domitian, also known as the Circus Agonalis, was located to the north of the Campus Martius in Rome, Italy. The Stadium was commissioned around AD 80 by Emperor Titus Flavius Domitianus as a gift to the people of Rome and was used almost entirely for athletic contests. In Christian tradition, Agnes of Rome was martyred there.

Domitian was Roman emperor from 81 to 96. The son of Vespasian and the younger brother of Titus, his two predecessors on the throne, he was the last member of the Flavian dynasty. Described as "a ruthless but efficient autocrat", his authoritarian style of ruling put him at sharp odds with the Senate, whose powers he drastically curtailed.
