Robert Reese Parrish (January 4, 1916 – December 4, 1995) was an American film editor, director, and former child actor. He won an Academy Award for Best Film Editing for his work on Body and Soul (1947).

Born in Columbus, Georgia, Parrish was the son of Coca-Cola salesman Gordon R. Parrish and actress Laura Virginia (née Reese) Parrish. In 1924 the Parrish family relocated to Hollywood, "about 400 yards from Paramount Studios", where Robert's mom was "a card-carrying movie mother". She helped all four of her children obtain movie work. Robert and his sisters Beverly and Helen became child actors in the late 1920s.

Parrish made his film debut in the Our Gang short Olympic Games (1927). He then appeared in the classic Sunrise: A Song of Two Humans (1927); Yale vs. Harvard (1928), another Our Gang short; Mother Machree (1928) and Four Sons (1928) from John Ford; Speedy (1928) with Harold Lloyd; Riley the Cop (1928) for Ford; The Iron Mask (1929) with Douglas Fairbanks; The Divine Lady (1929); The Racketeer (1929); Anna Christie (1930) with Greta Garbo; the anti-war film All Quiet on the Western Front (1930); The Big Trail (1930) with John Wayne; Up the River (1930) for Ford; The Right to Love (1930) with Ruth Chatterton; and Charles Chaplin's City Lights (1931) (as one of the peashooting newsboys who torments Chaplin's "Little Tramp" character).

As a young actor, Parrish was encouraged by John Ford to work behind the scenes, and first gained experience as an editing apprentice on The Informer. Parrish was Ford's assistant editor for Mary of Scotland (1936), and obtained additional sound and editing jobs on Stagecoach (1939), Young Mr Lincoln (1939), Drums Along the Mohawk (1939), The Grapes of Wrath (1940), The Long Voyage Home (1940), and Tobacco Road (1941).

Both Ford and Parrish served in the U.S. Navy during World War II, and together they produced documentary and training films, including The Battle of Midway (1942), How to Operate Behind Enemy Lines (1943), German Industrial Manpower (1943), and December 7th: The Movie (1943). Parrish also edited George Stevens' That Justice Be Done (1945) and The Nazi Plan (1945).

After Parrish was discharged from the Navy, he co-edited with Francis Lyon the Robert Rossen-directed boxing drama Body and Soul (1947). Parrish and Lyon received an Academy Award for their work.

Parrish went on to edit A Double Life (1947) for George Cukor, No Minor Vices (1948) for Lewis Milestone, and Caught (1949) for Max Ophüls.
