Frank S. Ferguson (December 25, 1899 – September 12, 1978)[1] was an American character actor with hundreds of appearances in both film and television.

Ferguson's best known role was as the Swedish ranch handyman, Gus Broeberg, on the CBS television series, My Friend Flicka,[6] based on a novel of the same name.

In 1952, Ferguson played the part of a music professor at Pomona College in the second of two short films starring Jascha Heifetz, produced by Rudolph Polk and Bernard Luber.

He guest starred on other series, including the syndicated Gunsmoke, Cheyenne, Rescue 8, Bat Masterson, Whirlybirds, and The Everglades; NBC's The Restless Gun, Riverboat, Overland Trail, National Velvet, and Mr. Novak; ABC's The Real McCoys, The Rifleman, The Alaskans, Target: The Corruptors, The Asphalt Jungle, and Mr. Smith Goes to Washington; and CBS's General Electric Theater (hosted by Ronald W. Reagan), and The Texan, starring Rory Calhoun.

Ferguson appeared twice in 1956 as Henry Murdock (a name similar to his character in The Pride of the Family) on the syndicated western-themed crime drama, Sheriff of Cochise.

He guest starred in all three of Rod Cameron's crime series, City Detective (1955), State Trooper (in the 1957 episode "No Blaze of Glory", the story of a presumed arson case with a surprise ending, co-starring Vivi Janiss as his wife) and Coronado 9 (1960).
