The O.S.S. D-502 Junk Guild, also known as the "Junk X'press" Guild, was a group of junk dealers active in the Dantooine system during the Galactic Civil War.
The O.S.S. D-502 Junk Guild operated in the Dantooine system. They were based in the Area D-502 but were also present in the Wall of Dantooine asteroid field and near the destroyed Legacy YT Indigo Blue station. Due to the lack of protection provided by the Empire, the O.S.S. D-502 junk dealers had allied with a group of scientists, the Aii`tkian Anthropologists, to protect themselves against the Zel'iphian Slave Traders Guild.
In space, Junk X'press" Guild pilots flew M3-A Scyk fighters and M12-L Kimogila heavy fighters.
Around the time of the Battle of Yavin, the O.S.S. Junk Guild and the Aii`tkian Anthropologists discovered a new strain of copper in the Dantooine system's Area D-502. Aii`tkian scientists then investigated whether it was worth to be used to manufacture starship parts.

D-502 Junk Guild appeared in the 2003 video game Star Wars Galaxies: An Empire Divided, a massively multiplayer online roleplaying game developed by Sony Online Entertainment and published by LucasArts, prior to its closure on December 15, 2011.
