This is a list of Roman Emperors with the dates they controlled the Roman Empire.

(Note that, contrary to popular belief, Julius Caesar was never Emperor (princeps), although he was named dictator for life in 45 BC (but was not the first Roman to hold that title) and was regarded as such by Roman historians.)

For the worship of the Roman Emperor as a god, see imperial cult.
