Barbara "Bobby" McLean (November 16, 1903 – March 28, 1996) was an American film editor with 62 film credits.

In the period Darryl F. Zanuck was dominant at the 20th Century Fox Studio, from the 1930s through the 1960s, McLean was the studio's most prominent editor and ultimately the head of its editing department. She won the Academy Award for Best Film Editing for the film Wilson (1944). She was nominated for the same award another six occasions, including All About Eve (1950). Her total of seven nominations for Best Editing Oscar was not surpassed until 2012 by Michael Kahn.

She had an extensive collaboration with the director Henry King over 29 films, including Twelve O'Clock High (1949). Her impact was summarized by Adrian Dannatt in 1996 who wrote that McLean was "a revered editor who perhaps single-handedly established women as vital creative figures in an otherwise patriarchal industry."

McLean was born in Palisades Park, New Jersey; she was the daughter of Charles Pollut, who ran a film laboratory. As a child she worked on release prints from the adjacent studio of E.K. Lincoln in Grantwood, who was an early producer of films. No doubt the early experience in processing of film was helpful to McLean when she became an assistant film editor, but McLean later commented that her musical training as a child also was very important.

In 1924, she married J. Gordon McLean, who was a film projectionist and later, a cameraman. After marrying, the couple moved to Los Angeles, California. McLean found work as an assistant editor at First National Studio. She subsequently joined Twentieth Century Pictures, where initially, she assisted the editor Alan McNeil. In 1933, she received her first editing credit for Gallant Lady; her work on Les Misérables (directed by Richard Boleslawski, 1935) was nominated for the Academy Award for Film Editing.

In 1935, 20th Century Pictures merged with the Fox Film Corporation to form 20th Century Fox. Darryl F. Zanuck was the head of the merged studio, and McLean became the chief editor under his sponsorship. John Gallagher has written that "Studio chief Darryl F. Zanuck was himself a brilliant editor and maintained the best editorial department in Hollywood."

McLean retained this position until her retirement in 1969. McLean had more authority over the editing of the studio's films than is typical for contemporary film editors; as Lizzie Francke described it: "McLean worked during a period when the editor was often left to his or her own devices in the cutting room. The pressures of production turn-over during the hey-day of the studio system often meant that the director could not be around to supervise since they were on to their next production."

Darryl Zanuck not only trusted McLean with the editing of 20th Century Fox's more important projects, he depended on her judgment in many other areas of filmmaking, including casting and production. In 1940, a Los Angeles Times story commented that "Barbara McLean, one of Hollywood's three women film editors, can make stars — or leave their faces on the cutting room floor."
