Francesco Maria Niccolò Gabburri (17 December 1675 – 1742) was a Florentine diplomat, painter, art collector, and biographer of artists.

Niccolò Gabburri was a prominent broker for artists and collectors in Florence during the first half of the 18th century.

He painted various works in Rome, including the dome of Santa Rita da Cascia alle Vergini.

His collection of drawings and prints was bought by William Kent in 1758, and sold in London.

He wrote an unpublished Vite de' pittori relating mainly biographical details of Florentine artists.
