Venetian red is a light and warm (somewhat unsaturated) pigment that is a darker shade of scarlet, derived from nearly pure ferric oxide (Fe₂O₃) of the hematite type. Modern versions are frequently made with synthetic red iron oxide.

Historically, Venetian red was a red earth color often used in Italian Renaissance paintings. It was also called sinopia, because the best-quality pigment came from the port of Sinop in northern Turkey. It was the major ingredient in the pigment called cinabrese, described by the 15th-century Italian painter and writer Cennino Cennini in his handbook on painting, Il Libro dell'Arte. Cennini recommended mixing Venetian red with lime white, in proportions of two to one, to paint the skin tones of faces, hands and nudes.
