The fictional universe of the Star Wars franchise features multiple planet and moons. While only the feature films and selected other works are considered canon to the franchise since the 2012 acquisition of Lucasfilm by The Walt Disney Company, some canon planets were first named or explored in works from the non-canon Star Wars expanded universe, now rebranded Star Wars Legends.

In the theatrical Star Wars films, many settings for scenes set on these planets and moons were filmed at real-world locations on Earth. For example, the resort city of Canto Bight located on the planet Cantonica, seen in Star Wars: The Last Jedi (2017), was filmed in Dubrovnik, Croatia.

The Star Wars galaxy contains several broad sub-regions. Their exact definitions fluctuated somewhat during the Legends continuity, but were later formally updated by the new canon continuity when Disney purchased Lucasfilm. The new canon map is broadly similar to the later versions of the Legends galactic map.

As a general rule, most of the galaxy's wealth, power, and population are concentrated near the middle of the galactic circle – the "Core Worlds". The first major interstellar powers in the core are stated to have risen many millennia ago, gradually coalescing into the early Galactic Republic, with its capital at Coruscant. Waves of colonization (and conquest) by the Republic gradually spread outward from the Core, into the sparser systems at the galaxy's edge, such as Tatooine. Worlds of the Outer Rim are rich in raw resources but lack the population, infrastructure, or political power of the Core. Major galactic sub-regions are further divided into quadrants, sectors, etc., down to individual star systems and planets.

Dathomir has not been a contender in any CBUB matches.
