Colonial One is the name of a fictional space vessel featured in the re-imagined Battlestar Galactica television franchise. It first appeared in the two-part miniseries event on the Sci-Fi Channel in 2003, and made appearances in the regular Battlestar Galactica TV series.
Colonial One was the capital ship of the Colonial Fleet, though it was not a warship such as a Battlestar. It became the primary base of operations for the heads of state of the Twelve Colonies, following the attack on Caprica by the Cylons. Newly sworn-in Colonial President Laura Roslin maintained her office on Colonial One, along with her entourage, which consisted of assistant Billy Keikeya, Chief of Staff Tory Foster, and Roslin's spiritual advisor, Elosha.
