"Blue Harvest" is the hour-long season premiere of the sixth season of the American animated television series Family Guy, and the first part of the series' Laugh It Up, Fuzzball trilogy. It originally aired on Fox in the United States on September 23, 2007. The episode is a retelling and parody of the 1977 blockbuster film Star Wars, recasting the show's characters as Star Wars characters, created with permission from Lucasfilm on the condition that the characters look exactly as they do in the movies. The plot follows Peter as he retells the story of Star Wars while the electricity is out in their house.

The title is a reference to the working title of Return of the Jedi. The episode was written by Alec Sulkin and directed by Dominic Polcino, and guest-stars Chevy Chase, Beverly D'Angelo, Mick Hucknall, Rush Limbaugh, and Judd Nelson.
