Fisher first guest starred on Family Guy in 2005, playing Angela, Peter Griffin's supervisor at the brewery, and voiced the character in 20 episodes since -- most recently last season in an episode that aired on Jan. 3.
"Carrie Fisher was smart, funny, talented, surprising, and always a hell of a fun time to be around. Family Guy will miss her immensely," Seth MacFarlane, who created Family Guy and voices many of the characters on the show, tweeted on Tuesday.
Fisher died on Tuesday after going into cardiac arrest on a flight from London to Los Angeles last week. She was in the U.K. filming an episode of the Amazon series Catastrophe. She was 60 years old.
In addition to her appearances on Family Guy and Catastrophe, Fisher had also completed filming on Star Wars: Episode VIII, reprising her role as Princess Leia.
Family Guy wasn't the only sitcom Fisher guest starred on throughout her career. The actress also appeared in a memorable episode of 30 Rock, starring opposite Tina Fey.
