Childebert I (c.  496 – 13 December 558) was a Frankish King of the Merovingian dynasty, as third of the four sons of Clovis I who shared the kingdom of the Franks upon their father's death in 511.

In the partition of the realm, Childebert received as his share the town of Paris, the country to the north as far as the river Somme, to the west as far as the English Channel, and the Armorican peninsula (modern Brittany).

The representative presented a pair of scissors and a sword, offering her the choice to shear the three young boys, thereby depriving them of the long hair considered a symbol of royal power, or to have them killed.

When Witiges, the king of the Ostrogoths, ceded Provence to the Franks in 535, the possession of Arles and Marseille was guaranteed to Childebert by his brothers.

Gregory of Tours, a contemporary Neustrian, cites Childebert as saying: "Velim unquam Arvernam Lemanem quae tantae jocunditatis gratia refulgere dicitur, oculis cernere" ("Would that I could set eyes on the Auvergne Limagne, which is spoken of so highly").

Childbert was also one of the more religious of the sons of Clovis, cooperating with his brothers, rescuing his sister, and constructing the famous monastery of Saint Vincent to house his relics.
