The Six Million Dollar Man is an American science fiction and action adventure television series, running from 1973 to 1978, about a former astronaut, USAF Colonel Steve Austin, portrayed by Lee Majors. After being seriously injured in a NASA test flight crash, Austin is rebuilt (at considerable expense, hence the title of the series) with bionic implants that give him superhuman strength, speed and vision. Austin is then employed as a secret agent by a fictional U.S. government office titled OSI. The series was based on Martin Caidin's 1972 novel Cyborg, which was the working title of the series during pre-production.

Following three television films intended as pilots, which all aired in 1973, The Six Million Dollar Man television series aired on the ABC network as a regular episodic series for five seasons from 1974 to 1978. Steve Austin became a pop culture icon of the 1970s.

A spin-off television series, The Bionic Woman, featuring the lead female character Jaime Sommers, ran from 1976 to 1978. During this time, several crossover episodes were produced. Three television movies featuring both bionic characters were also produced from 1987 to 1994.
