Aigueblanche (French pronunciation: [ɛɡblɑ̃ʃ]; Arpitan: Èguablantse) is a former commune in the Savoie department in the Auvergne-Rhône-Alpes region in south-eastern France.

A nobleman from Savoy, he came to England as part of the party accompanying King Henry III's bride Eleanor of Provence.

He then served the king for a number of years as a diplomat, helping to arrange the marriage of Prince Edward.

Peter became embroiled in King Henry's attempts to acquire the kingdom of Sicily, and Peter's efforts to raise money towards that goal brought condemnation from the clergy and barons of England.

When the barons began to revolt against King Henry in the late 1250s and early 1260s, Peter was attacked and his lands and property pillaged.
