Dagobah is a solar system in the Star Wars films, The Empire Strikes Back and Return of the Jedi. It also appears in a deleted scene from Revenge of the Sith. Yoda went into exile on Dagobah after a lightsaber battle with Darth Sidious.

The planet shown in Dagobah, in the Sluis sector, is a world of murky swamps, steaming bayous, and petrified forests, resembling Earth during the Carboniferous Period.

In the Star Wars storyline, after the Great Jedi Purge and his subsequent failure to defeat Darth Sidious, Jedi Master Yoda went into voluntary exile on Dagobah. Here, Yoda lived near a cave infused with the dark side of the Force, which kept him from detection by Emperor Palpatine.

In The Empire Strikes Back, Luke Skywalker is directed by the ghost of Obi-Wan Kenobi, to seek Yoda on Dagobah. After training with Yoda, Skywalker leaves Dagobah early to rescue his friends Han Solo, Princess Leia, and Chewbacca, whom he senses are in danger on the planet Bespin. Skywalker also briefly returns to Dagobah in Return of the Jedi, in which he has a final conversation with Yoda before Yoda's death. Luke then speaks to Obi-Wan Kenobi's ghost about the conflicting stories of Luke's parentage.
