Pierre Dubois (c. 1255 – after 1321), a French publicist in the reign of Philip the Fair, was the author of a series of political pamphlets embodying original and daring views.
Dubois was known to Jean du Tillet in the 16th, and to Pierre Dupuy in the 17th century, but remained practically forgotten until the middle of the 19th century, when his history was reconstructed from his works. He was a Norman by birth, probably a native of Coutances, where he exercised the functions of royal advocate of the bailliage and procurator of the university.
