Henri Gouraud (born 1944) is a French computer scientist. He is the inventor of Gouraud shading used in computer graphics. He is the great-nephew of general Henri Gouraud.

During 1964–1967, he studied at École Centrale Paris. He received his Ph.D. from the University of Utah College of Engineering in 1971, working with Dave Evans and Ivan Sutherland, with his dissertation titled Computer Display of Curved Surfaces.

In 1971, Gouraud made the first computer graphics geometry capture and representation of a human face in wire-frame model, and applied his shader to produce the famous human face images showing the effect of his shading, which were done using his wife Sylvie Gouraud as the model.
