The Second Foundation is an organization that figures significantly in Isaac Asimov's Foundation series.


The Second Foundation was set up in parallel with the First Foundation by Hari Seldon, the creator of Psychohistory. This organization was shrouded in secrecy from it's very beginning, and was said to be located at 'galaxy's end'.

By the end of the original trilogy, we learn that the Second Foundation is really an organization of Psychohistorians slaving for preservation of the Seldon Plan, based on Trantor, the old Imperial capital.
