Documenting one of the most pivotal galactic conflicts in Star Wars history, Star Wars: The Clone Wars takes place on a wide spread of different planets, though some become more important than others. The Clone Wars lasted for three years and spread throughout the galaxy, with important battles taking place from the Core Worlds to the Outer Rim. Many planets became battlegrounds, though not all these battles were highly memorable. Even then, some planets that saw little to no physical conflict played key roles in the Clone Wars, particularly for political reasons.

The following planets were selected as the most important for several reasons, the first being their significance to The Clone Wars in real life. Some of these planets are important simply because of how fans remember and engage with them, all because of this animated Star Wars TV show. Another important factor is, of course, how they function within the Star Wars narrative.
