Maximinus Thrax (Latin: Gaius Julius Verus Maximinus Augustus; c. 173 – 238), also known as Maximinus I, is Roman Emperor from 235 to 238.

Maximinus is described by several ancient sources, though none are contemporary except Herodian's Roman History.

Maximinus is the first emperor never to set foot in Rome.

He is the first of the so-called barracks emperors of the 3rd century; his rule is often considered to mark the beginning of the Crisis of the Third Century.

He dies at Aquileia whileattempting to put down a Senatorial revolt.
