Charibert I (French: Caribert; Latin: Charibertus; c. 517 – December 567) was the Merovingian King of Paris, the second-eldest son of Chlothar I and his first wife Ingund.

Her influence in the Kentish court was instrumental in the success of St. Augustine of Canterbury's mission in 597, effecting the conversion to Christianity of the first Anglo-Saxon ruler.

In 556, Chlothar sent his sons Charibert and Guntram (his youngest) against their stepmother, "Chunna," and younger stepbrother, "Chramn," who were in revolt.

However, a thunderstorm prevented any engagement, and Chramn (who was hiding out in Black Mountain) sent forged letters to his brothers (Charibert and Guntram) in which he falsely reported the death of their father (Chlothar).

His surviving queen (out of four), Theudechild, proposed a marriage with Guntram, though a council held at Paris in 557 had outlawed such matches as incestuous.
