Peter de Ramsay [Ramsey] (died 1256) was a 13th-century cleric based inScotland. His background and origins are obscure. He was the son of a "cleric in minor orders" and an unmarried girl and, according toJohn of Fordun, he was of "noble birth". He was probably the son of Ness de Ramsey, a baron ofFife.

The first notice of him comes in 1247 when, as a meredeacon, he is elected to succeedRadulf de Lamley asBishop of Aberdeen. Thechapter ofAberdeen wrote to the Pope requestingpapal dispensation for Ramsay'sillegitimacy as well as permission for theconsecration to take place inScotland. Upon receiving news of Ramsay's consecration,Pope Innocent IV wrote toDavid de Bernham,Bishop of St Andrews,Clement,Bishop of Dunblane, andAlbin,Bishop of Brechin, delegating the matter to them and instructing these bishops to make their own judgment on the matter, after which, they were to receive Ramsay's oath in his name.

The result of this is shown by Ramsay's successful accession to the bishopric. During his episcopate he became one of the royal councillors appointed byHenry III of England in 1255 for the minority of KingAlexander III of Scotland. He sanctionedAlan Durward's endowment of a chaplaincy of "Logydurnach" (Logie-durno) in 1251, and was alleged have sanctioned aconstitution for hisdiocese. He died in late 1256.
