Mark Trail was an American radio series that included two different adaptations based on the popular comic strip by Ed Dodd. The series aimed at a young audience and revolved around adventure stories, following the hero Mark Trail, a forest ranger who battled the elements and fought enemies of man and nature, while also teaching his friends about the wilderness. Each episode featured thrilling adventures and combined the qualities of J. Edgar Hoover and Robin Hood. This format provided intelligent entertainment to many children and captured their imaginations by giving them the chance to learn about wild America.

The first Mark Trail series aired on the Mutual Broadcasting System from January 30, 1950, to June 8, 1951, with a total of 174 episodes. The show was sponsored by Kellogg's Pep cereal. The second series aired on ABC Radio from September 18, 1950, to June 27, 1952, with a total of 125 episodes. While only a handful of the 15-minute episodes from the second series are known to have survived, the Minneapolis-St. Paul public radio station KFAI aired another Mark Trail Radio Theatre series from 1991 to September 2002. This series included 228 weekly installments and 17 adventures. Matt Crowley, Staats Cotsworth, and John Larkin were notable actors who played Mark Trail, while Jackson Beck provided the announcements and was known for his role as an announcer for the classic Superman serial on the radio.
