Roger Shepard (born January 30, 1929, Palo Alto, California, U.S.—died May 30, 2022, Tucson, Arizona) was an American psychologist and cognitive scientist known for his work in multidimensional scaling, the use of spatial models to show similarities and dissimilarities between data. He received a Ph.D. from Yale University and later worked at Bell Laboratories (1958–66) and taught at Stanford University (1968–96; thereafter professor emeritus). He also examined the phenomena of “mental rotation,” a form of image transformation. He received the National Medal of Science in 1995.
