Grand Admiral Thrawn (full name Mitth'raw'nuruodo) is a fictional character in the Star Wars franchise. Introduced in the 1991 Timothy Zahn novel Heir to the Empire, he is an Imperial military commander who has taken control of the Galactic Empire's remaining forces five years after the events of the 1983 film Return of the Jedi. Thrawn faces off against classic Star Wars characters Luke Skywalker, Princess Leia, Han Solo, Chewbacca, and Lando Calrissian in the Thrawn trilogy (1991–1993), but is ultimately defeated. He is seemingly resurrected in the Hand of Thrawn duology (1997–98), and his backstory is explored in various other novels, short stories, comics, and video games in the Star Wars Expanded Universe.
Though Lucasfilm rebranded the expanded universe works as Star Wars Legends in 2014 and declared them non-canon to the franchise, Thrawn was reintroduced in the third season of the 3D CGI animated television series Star Wars Rebels, voiced by Lars Mikkelsen. The character is also featured in a 2017 novel titled Thrawn, written by Zahn.
Thrawn has been called one of the most significant and popular characters in the Legends continuity, and several Star Wars action figures and other merchandising have been produced of the character.
