Pelios Station was a Federation space station located in the Pelian system in the Alpha Quadrant. It orbited the star Pelios at a distance of twelve light-minutes, between its second and third planet. The station was home to approximately two hundred and fifty crew.
Pelios Station was constructed following a petition for help from the Bactricans during that race's conflict with the Tzenkethi. The station was not only a diplomatic base, but also served in a support capacity for the mining operations in the Pelian system.
Negotiations for the Bactricans entry into the Federation took place on Pelios Station, as did the Federation's first contact with the Azziz. Pelios Station was also where Benjamin Sisko first met Ambassador Curzon Dax. (DS9 - The Lives of Dax short story: "The Music Between the Notes", DS9 episode: "Invasive Procedures")
