Charlie's Angels: Season One was the first season of the 1970s television series, Charlie's Angels. The season starred Kate Jackson, Farrah Fawcett-Majors, Jaclyn Smith, David Doyle, and the voice of John Forsythe. The season aired from September 22, 1976 to May 4, 1977, with a total of 23 episodes.

Although the pilot episode featured an extra male liaison named Scott Woodville, he was dropped for the series as it was felt there was no need for Charlie to have two male liaisons. It was also felt that the character of Woodville was rather too severe, whereas Bosley was someone the writers could use to add humor to the episodes.

The pilot, which aired on March 21, 1976, was nearly two hours long, and the succeeding episodes were between 48 and 50 minutes in length. Ratings for the first season were extremely high, finishing in the #5 slot. All three female leads were launched to greater heights in their career, with Fawcett-Majors proving to be the most popular of the trio. Although Jackson and Smith were overshadowed by Fawcett-Majors they have equally stood the test of time, and both have also been cited as "fan favorites."
