Jean-Baptiste Boyer, Marquis d'Éguilles (1650–1709) was a French aristocrat, lawyer, and engraver.

His love of the arts led him into an intimacy with the principal artists of his time, particularly with Pierre Paul Puget, the celebrated sculptor, with whom he went to Italy.

He amassed a large collection of pictures, sculptures, etc., and published the prints in two volumes; six of the plates were engraved by himself.

He married Jeanne-Marie Surle, Lady of Argens (circa 1650-circa 1720), on 1 April 1671.

They had eleven children: He died in Aix-en-Provence, at the age of fifty-eight.
