Grand Admiral Thrawn  is a fictional character and a major antagonist 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.

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.
