Luke Skywalker is a fictional character and the protagonist of the original film trilogy of the Star Wars franchise created by George Lucas. Portrayed by Mark Hamill, Luke first appeared in Star Wars (1977), and he returned in The Empire Strikes Back (1980) and Return of the Jedi (1983). Over three decades later, Hamill returned as Luke in the Star Wars sequel trilogy, with a cameo in The Force Awakens (2015) before playing a major role in The Last Jedi (2017) and The Rise of Skywalker (2019). He later played a digitally de-aged version of the character in the Disney+ series The Mandalorian, appearing in the second-season finale, which premiered in 2020, and The Book of Boba Fett, in the sixth episode, released in 2022.

The original Star Wars trilogy, formerly marketed as the Star Wars Trilogy, is the first set of three films produced in the Star Wars franchise, an American space opera created by George Lucas. It was produced by Lucasfilm and distributed by 20th Century Fox, and consists of Star Wars (1977), The Empire Strikes Back (1980) and Return of the Jedi (1983). Beginning in medias res, the original trilogy serves as the second act of the nine-episode Skywalker Saga. It was followed by a prequel trilogy between 1999 and 2005, and a sequel trilogy between 2015 and 2019. Collectively, they are referred to as the "Skywalker Saga" to distinguish them from spin-off films set within the same universe.
