Pierre-Gabriel Buffardin (Toulon, 24 March 1693 - Paris, 13 January 1768) was a French flutist and composer of the late Baroque period.

He was a son of Jean-Joseph Buffardin (Vaison-la-Romaine, 22 July 1664 - Avignon, 28 August 1726), an instrument maker[citation needed].

Buffardin was the principal flutist of the orchestra (Hofkapelle) at the court of the Elector of Saxony in Dresden from 1715 to 1749.

Quantz said of Buffardin: "Il ne jouait que des choses rapides: car c'est en cela qu'excellait mon maître."

Antoine Mahaut claimed that Buffardin was the inventor of the flute's screw cap and the foot register; it remains uncertain whether or not a transverse flute stamped "Buffardin le fils" (discovered in 2015) may be attributed to him or a relative (see Giovanni Tardino, note for recording Bach: Sonate a cembalo obligato e traversiere solo, HRA (HiResAudio), 2018).
