"Blue Harvest" is the hour-long 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 sixth season of Family Guy first aired on Fox from September 23, 2007, to May 4, 2008. The season included 12 episodes and was shortened due to creator Seth MacFarlane's participation in the 2007–2008 Writers Guild of America strike, which resulted in Fox airing episodes without MacFarlane doing the final work. The episode "Lois Kills Stewie" was the last episode completed before the strike. When the strike ended in February 2008, Fox had already aired three episodes without any input from MacFarlane.
