A shadowport was essentially a clandestine spaceport that operated outside the law, typically being unrecorded in official documentation.

During the era of the Galactic Civil War, the one situated on Darlyn Boda functioned as a well-known sanctuary for black-market traders. Another such port, found on Savareen, was located within an obsolete refinery.
Hutt Space was home to numerous planets recognized as shadowports. For instance, both Nar Haaska and Nar Shaddaa operated as shadowports due to the pervasive criminal enterprises occurring on those worlds, backed by the Hutt clans.
The most significant concentrations of planets lacking official registration or taxation were situated along the Hydian Way, a prominent Hyperspace route in the galaxy's northern regions. Among the most vital ports for criminals and smugglers were Ord Mantell, Borgo Prime, and Port Haven.
