Teia, also known as Teja, Theia, Thila, Thela, and Teias, was the last Ostrogothic King of Italy. He led troops during the Battle of Busta Gallorum and had noncombatant Romans slaughtered in its aftermath. In late 552/early 553, he was killed during the Battle of Mons Lactarius. Archaeological records attesting to his rule show up in coinage found in former Transalpine Gaul.

The Ostrogoths were a Roman-era Germanic people. In the 5th century, they followed the Visigoths in creating one of the two great Gothic kingdoms within the Western Roman Empire, drawing upon the large Gothic populations who had settled in the Balkans in the 4th century. While the Visigoths had formed under the leadership of Alaric I, the new Ostrogothic political entity which came to rule Italy was formed in the Balkans under Theodoric the Great.
