Theuderic I (c.485 – 533/4) is the Merovingian king of Metz, Rheims, or Austrasia—as it is variously called—from 511 to 533 or 534.
He is the son of Clovis I and one of his earlier wives or concubines.
He inherits Metz in 511 at his father's death.
In accordance with Salian tradition, the kingdom is divided between Clovis's four surviving sons: Childebert I in Paris, Chlodomer in Orléans, and Clotaire I in Soissons.
Early in his reign, he sends his son Theudebert to battle the Scandinavian King Chlochilaich (Hygelac of Beowulf fame) who had invaded his realm.
