Gabriel Van Dievoet (/ˈdiːvʊt/, 12 April 1875 – 17 November 1934) was a Belgian decorator and Liberty style sgraffitist.

He was the son of Leon Van Dievoet, ship-owner and maritime-agent, and of Hermine Straatman; and the grandson of Eugene van Dievoet and Hortense Poelaert (sister of the famous architect Joseph Poelaert).

After studying at the Académie Royale des Beaux-Arts in Brussels at the same time as Paul Cauchie, he opened his decorative arts workshop and started collaborating with many Art Nouveau or Late Eclectic architects, such as Victor Boelens, De Kock, Georges Delcoigne, Edouard Elle, Guillaume Low, Georges Peereboom, Edouard Pelseneer, Albert Roosenboom, Fernand Symons, Joseph Van Neck, Armand Van Waesberghe and his own brother, Henri Van Dievoet.

He was often inspired by the artworks created during the Arts and Crafts Movement, such as the decorations of the "Maison dorée" (Gold House) in the town of Charleroi.

He also designed the sgraffito decorations of the following monuments: He also produced several paintings and watercolours; the prints room ("cabinet des estampes") at the Royal Library of Belgium still preserves his etching entitled "Head of Lion" (reference: F 41265).
