The House of Theodosius was a Roman family that rose to eminence in the waning days of the Roman Empire.

Its founding father was Flavius Theodosius (known to us as Count Theodosius), a great general who had saved Britannia from the Great Conspiracy. His son, Flavius Theodosius was made co-emperor of the Western Roman Empire in 378, and became the last emperor of a unied Roman Emperor in 392, until his death in 395.
