The Byzantine senate or Eastern Roman senate was a continuation of the Roman Senate, established in the 4th century by Constantine I. It survived for centuries, but the senate's powers varied greatly during its history and gradually diminished until its eventual disappearance in the 14th century.

The Roman Senate was the highest and constituting assembly of ancient Rome and its aristocracy. With different powers throughout its existence it lasted from the first days of the city of Rome as the Senate of the Roman Kingdom, to the Senate of the Roman Republic and Senate of the Roman Empire and eventually the Byzantine Senate of the Eastern Roman Empire, existing well into the post-classical era and Middle Ages.
