Andelot-Blancheville (in French pronounced as /ɑ̃dlo blɑ̃ʃvil/) is a commune in the Haute-Marne department in the Grand Est region in northeastern France. It lies on the river Rognon, a tributary of the Marne.
It was the site of an important pact, known as the treaty of Andelot, by which king Guntram of Burgundy and queen Brunehaut agreed that Guntram was to adopt her and Sigebert I of Austrasia's son Childebert II as his successor, and ally himself with Childebert against the revolted leudes.
It also brought about the cession of Tours by Guntram to Childebert II.[2]
