Philip de Carteret (died 1500) was the eighth Seigneur of Saint Ouen.
According to a biased non-contemporary account of Baker's governorship, Philip de Carteret opposed the alleged cruelty of the rule of Matthew Baker as Governor of Jersey, who had been appointed with vice-regal Powers in all but name.
De Carteret was imprisoned in Mont Orgueil to await trial by combat.
According to a chronicle of events, – written by a member of the de Carteret family some 70 years later – his wife Margaret, who had only recently given birth, secretly took a boat to the English mainland to convince King Henry VII of her husband's innocence.
Henry VII was not absolutely convinced of de Carteret's loyalty, however, and placed him under a Bond of £1,000 as surety for his future good conduct.
