Peter of Aigueblanche (or Peter of Aquablanca or Peter d’Aigueblanche or Peter de Aquablanca; died 27 November 1268) was a medieval Bishop of Hereford. A nobleman from Savoy, he came to England as part of the party accompanying King Henry III's bride Eleanor of Provence. He entered the royal service, becoming bishop in 1241.

Royal service Peter continued to receive gifts from the king, including market rights, and the ability to take timber from the royal forests. In August, Peter was present at the royal court at Shrewsbury which made peace with the Welsh. In the autumn, Henry again attempted to have him translated to another see, by having him moved to London, which was once more unsuccessful. He then served as a
