The Adventures of Harry Lime, also known as The Lives of Harry Lime, was a British old-time radio show produced during the 1951-1952 season starring Orson Welles as the charming and mischievous Harry Lime. A prequel to the 1949 film The Third Man, the series followed Lime's exploits as a con-artist in a lighter tone than the original film.

Produced by Harry Alan Towers and his company Towers of London, the show was syndicated and broadcast internationally. The full series was aired in the United States, but the BBC in the UK aired only 16 episodes, marking the first time they would broadcast a dramatic series they did not produce.

The series featured 52 episodes, providing 24 hours and 10 minutes of playtime, capturing the adventures of Orson Welles as Harry Lime engaging in a series of daring escapades with a touch of humor and wit.
