The Security Council was a group amongst the Galactic Senate that was charged with overseeing the security of the Galactic Republic.

Among the Security Council's list of powers was the authority to initiate Order 65, a contingency command instructing all units of the Grand Army of the Republic that the Supreme Chancellor had been declared a threat to the Galactic Republic and was to be apprehended or terminated if necessary. Unlike its counterpart, Order 66, Order 65 was never enacted.
