Giovanni Marco Pitteri was an Italian engraver of the late-Baroque period in his native Venice.
He made densely incised, with nearly photographic quality shading, engraved portraits. He is said to have trained under Giovanni Antonio Faldoni, and engraved in the style of Mellan. He engraved a drawing of "St. Phillip" by Piazzetta, in whose studio he worked. He had as one of his pupils Giovanni Domenico Lorenzi.
