Pierre du Cambout (14 November 1636 – 5 February 1706) was a French prelate. He was a grandson of Pierre Séguier and held many important benefices - abbot of Jumièges, in 1641, of Saint-Victor, in 1643, canon of Paris, and first king's almoner in 1663. He was finally Grand Almoner of France and bishop of Orléans from 1665 to 1706, as well as (in a surprise appointment) being made cardinal priest of Trinità dei Monti.
Dangeau reported:
Saint-Simon[1] wrote of him:
One of his successors removed the epitaph from the cardinal's tomb "since people were going there to pray to God, as at a saint's tomb".[2] His nephew Henri Charles du Cambout de Coislin was also a bishop.
