The 30 Rock star added that he thinks his movie career has been a failure.
Speaking to Men's Journal, he said: "I don't have any interest in acting anymore. Movies are part of my past. It's been 30 years. I'm not young, but I have time to do something else.
"It's a difficult thing to say, but I believe it: I consider my entire movie career a complete failure.
"I'll tell you why. The goal of moviemaking is to star in a film where your performance drives the film, and the film is either a soaring critical or commercial success, and I never had that."
Baldwin was recently confirmed as one of the hosts of next year's Oscars ceremony.
