Fisher, who died in 2016, is being added to the famous Hollywood tourist attraction on the unofficial Star Wars holiday May the Fourth — an allusion to the oft-quoted line from the films, "May the force be with you."
Her daughter, Billie Lourd, will accept the star, which is being placed alongside Fisher's co-stars Mark Hamill and Harrison Ford on the 6800 block of the boulevard, close to the location of the original film's premiere back in 1977.
Lourd wore metallic dress bearing her mother's portrait at the ceremony.
"My mom used to say you weren't actually famous until you became a Pez dispenser," she said, referencing a type of novelty candy dispenser that ejects small sweets from the heads of famous characters or cartoons.
"Well, people eat candy out of her neck every day. I say you aren't actually famous until you get a star on the Hollywood Walk of Fame," Lourd added.
"My mom is a double-whammy — a Pez dispenser and has a star on the Hollywood Walk of Fame now. Mama, you've made it," she added.
Mark Hamill, who played Luke Skywalker in the Star Wars franchise, honored the role she played in his life and remembered her feisty spirit.
"She played such a crucial role in my personal and professional life and both would have been far emptier without her. Was she a handful? Was she high-maintenance? No doubt! But everything would have been drabber and less interesting if she hadn't been the friend that she was," Hamill said.
Devotees celebrate Fisher's induction to Walk of Fame
Fans had campaigned for Fisher's inclusion in the Walk of Fame for years after Ford received his star in 2003 and Hamill got his in 2018.
Several people in the crowd dressed up as Star Wars characters, donning the costumes of famous droids like C-3P0 and R2-D2. Others wore Fisher's iconic braided, twin bun hairstyle that Princess Leia donned.
Performers can be given a Walk of Fame star if they are nominated, but they require a fee of $75,000 (€67,600) to make and maintain the actual star.
A number of events were planned to mark the occasion, with retailers also offering discounts on Star Wars merchandise. The Hollywood Chamber of Commerce also livestreamed Fisher's induction ceremony to the Walk of Fame at 11:30 a.m. Pacific Time (1830 UTC).
Not just Princess Leia
Fisher became a worldwide star when she took up the role of Leia Organa at just 19.
After starring in the original trilogy, she later reappeared in the second set of sequels as well as the Star Wars film "Rogue One" — giving her a total of six appearances in the Star Wars saga.
The actor also appeared in other cult movies such as "The Blues Brothers" and "When Harry Met Sally."
Fisher had bipolar disorder and drug addiction, which she talked about publicly. In 2016, Harvard University presented her with the "Lifetime Achievement Award in Cultural Humanism" for her public engagement.
Later that year, on December 27, she passed away after suffering a massive heart attack. She was 60 years old.
