What is the name of the Jedi master played by Alec Guinness in Star Wars?

The Jedi master played by Alec Guinness in Star Wars is Obi-Wan Kenobi.

In the original Star Wars trilogy, Obi-Wan first appears as an elderly hermit known as Ben Kenobi. He reveals his Jedi identity to Luke Skywalker and begins guiding Luke in the ways of the Force. Obi-Wan had previously trained Anakin Skywalker, Luke’s father, as a Jedi before Anakin became Darth Vader.

Alec Guinness portrayed Obi-Wan in the original trilogy: Star Wars (1977), The Empire Strikes Back (1980), and Return of the Jedi (1983). Ewan McGregor later played the younger Obi-Wan in the prequel trilogy and the 2022 television series Obi-Wan Kenobi.

A common mix-up is confusing Obi-Wan with Yoda, another Jedi master, or Luke Skywalker, whom Obi-Wan trains. Obi-Wan’s title is not merely honorary: within the story, he is a senior Jedi Master, mentor, and one of the last surviving Jedi after the Empire’s rise.
