Parley Edward Baer (August 5, 1914 – November 22, 2002) was an American actor in radio and later in television and film. Despite dozens of appearances in television series and theatrical films, he remains best known as the original "Chester" in the radio version of Gunsmoke, and as the Mayor of Mayberry (Roy Stoner) in The Andy Griffith Show.

Baer in the 1930s served on radio as director of special events for KSL. His first network show was The Whistler, which was soon followed by appearances on Escape (notably narrating "Wild Jack Rhett" and as the title patriot in an adaptation of Stephen Vincent Benét's "A Tooth for Paul Revere"), Suspense, Tales of the Texas Rangers (as various local sheriffs), Dragnet, The CBS Radio Workshop, Lux Radio Theater, The Six Shooter, and Yours Truly, Johnny Dollar, to name a few.
