Gordian I (Latin: Marcus Antonius Gordianus Sempronianus Romanus; c. 158 – April 238) was Roman emperor for 22 days with his son Gordian II in 238, the Year of the Six Emperors. Caught up in a rebellion against the Emperor Maximinus Thrax, he was defeated in battle and committed suicide after the death of his son, having had the second shortest reign in imperial history.
