Robert William Bischoff (January 28, 1899 – May 12, 1945) was an American film editor.
Born in Denver, Bischoff signed a contract with Fox in 1927 and started by editing three silent Western vehicles for Tom Mix — The Last Trail, Hello Cheyenne and Painted Post.
He worked uncredited on a number of films and received billing on others, such as Rackety Rax, a 1932 vehicle for Victor McLaglen.
Returning to Fox in 1939, now under the logo "20th Century Fox", he edited a number of big-budget productions — two vehicles for Shirley Temple — 1939's Susannah of the Mounties and 1940's The Blue Bird — as well as three Tyrone Power films — 1940's Brigham Young and The Mark of Zorro, along with 1941's Blood and Sand.
In May 1945, shortly after V-E Day, he became ill in his office and died at Bethesda Naval Medical Center at the age of 46.
