The name Leia is a girl's name of Hindi origin. Leia is ranked #321 on our popularity charts and is often added to lists like Fictional Princess Names and discussed in our forums with posts like "Girls Makeover - Two Middles".
From the experts:
This spelling variation of Leya was popularized by the Star Wars films, but is still firmly in the US Top 1000 many years later. It broke into the Top 500 for the first time in 2015, probably thanks to the release of The Force Awakens and has the trademarks of a trendy choice with the familiarity from the popular character. Leia continued its rise all the way up to Number 321 in 2016. This spelling is also probably preferred as it is clearer in pronunciation to the original Hindi name, Leya (which sometime gets pronounced Lee-ah).
