The "umbrella man", identified by the United States House Select Committee on Assassinations in 1978 as Louie Steven Witt, is a name given to a figure who appears in the Zapruder film, and several other films and photographs, near the Stemmons Freeway sign within Dealey Plaza during the assassination of John F.
Kennedy.
Witt is the subject of a 2011 documentary short, The Umbrella Man, by Errol Morris for The New York Times.
