Neimoidian space was a sector situated within the Colonies region of the galaxy. This sector encompassed the planet of Neimoidia, which served as the original homeworld for the Neimoidian species, along with their wealth-generating purse worlds like Cato Neimoidia, Deko Neimoidia, and Koru Neimoidia. In the time of the Clone Wars, it started as a neutral territory but later sided with the Confederacy of Independent Systems. Throughout the Outer Rim Sieges, Republic military groups were in the process of eliminating the remaining Separatist holdouts that were located in Neimoidian space.
