Hello Americans, a 1942-43 CBS Radio series, was created to promote inter-American understanding and friendship during World War II. Produced, directed, and hosted by Orson Welles, the show was made as part of Welles' contribution to the war effort, influenced by his interest in Latin and South American culture. Aired on Sundays at 8 p.m. ET, the series ran for 12 episodes, with its last broadcast on January 31, 1943. Sponsored by the Office of the Coordinator of Inter-American Affairs, it featured actors from Welles's Mercury Theatre repertory ensemble.

The show, with a generally lighthearted tone, had moments of editorial insertions on topics like racism and fascism. A key aspect of the program was portraying Central and South American countries as rich in history and culture. Developed in collaboration with the CIA, Hello Americans was inspired by a trip Orson Welles took to South America. It featured guest appearances by Hans Conried, Gerald Mohr, Laird Cregar, Agnes Moorehead, Ray Collins, and Carmen Miranda.
