Leia (also Leah) means "weary" in Hebrew or "flowers/garland of flowers" in Hawaiian. Princess Leia Organa — Senator of Alderaan, leader of the Rebel Alliance, and later General of the Resistance — is among the most influential heroines in modern American cinema since her introduction in Star Wars (1977) — portrayed by Carrie Fisher (1956-2016) across nine films from 1977 to 2019. Her opening hologram — "Help me, Obi-Wan Kenobi. You're my only hope" — and her white-robe-with-cinnamon-bun-hairstyle silhouette are among the most recognized images of late-20th-century pop culture. *Carrie Fisher was 19 when she filmed her role in Star Wars***; the name climbed the SSA charts steadily through the 2010s, breaking the US top 300 in 2017.
Subject of countless Star Wars histories and Carrie Fisher's memoirs Wishful Drinking (2008) and The Princess Diarist (2016).
In Pythagorean numerology the letters of Leia reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
