François Campion (Rouen 1686 - Paris 1747)>, (or pseudonym M. Abbé Carbasus) is a guitarist, theorbist, lutenist, French baroque composer and French theorist.
François Campion is generally considered the most important French Baroque guitarist after Robert de Visée.
He succeeds Maltot as a guitarist and theorist in the orchestra of the Royal Academy of Music from 1703 or 1704 to 1719.
Maltot transmits to him the rule of the octave which he will record later in his Traité d'Accompagnement (1716).
He received the title Master of guitar and theorbo at the Royal Academy of Music from King Louis XIV (it is thought that he benefited from the protection of the Duke of Noailles).
