I Led 3 Lives (also known as I Led Three Lives) is an American drama series syndicated by Ziv Television Programs from October 1, 1953, to January 1, 1956. The series stars Richard Carlson. The show was a companion piece of sorts to the radio drama I Was a Communist for the FBI, which dealt with a similar subject and was also syndicated by Ziv from 1952 to 1954.

The series was loosely based on the life of Herbert Philbrick, a Boston advertising executive who infiltrated the U.S. Communist Party on behalf of the FBI in the 1940s and wrote a bestselling book on the topic, I Led Three Lives: Citizen, 'Communist', Counterspy (1952). The part of Philbrick was played by Richard Carlson. The "three lives" in the title are Philbrick's outward life as a white-collar worker, his secret life as a Communist agent, and his even more secret life as an FBI operative helping to foil Communist plots.^[1] I Led 3 Lives lasted 117 episodes. Philbrick served as a technical consultant,^[2]: 37 with Carlson narrating each episode.^[2]: 86

The episodes often had very little to do with the actual events of Philbrick's life as related in his book—Philbrick is credited with only 5 of the 117 screenplays. Screenplays gradually became more and more outlandish, featuring, for example, such supposed "Communist plots" as the conversion of household vacuum cleaners (1942-1954 Electrolux) into tactical missile launchers with which the Communists intended to destroy America's Nike anti-aircraft defensive missiles, and the manufacturing of untraceable "ghost guns" (unserialized Colt M1911 .45 cal semi-automatics) with which the Communists intended to assassinate their political enemies.^{[citation needed]}

The series was honored by the Freedoms Foundation as the best television program of 1955.^[3]

The title of the TV series I Had Three Wives, which aired briefly in 1985, is a pun on the name of the original; it was an otherwise unrelated comedy-drama about a private detective's three ex-wives, who cooperate on cases.
