Herbert Earl Grier (July 3, 1911 — March 17, 1999) was an American electrical engineer. While starting his engineering career with MIT during the 1930s to 1940s, Grier co-invented a miniature stroboscope and handheld flash with Harold Edgerton and Kenneth Germeshausen. During World War II, Grier built a firing mechanism during the Manhattan Project that was used in the Fat Man bomb.

With EG&G, Grier was president until 1976 and served as a consultant from 1983 to 1994. Apart from electrical engineering, he took part in NASA safety boards that assessed Skylab and the preparation of the first Space Shuttle.
