terrorist organization

Many organizations that are accused of being a terrorist organization deny using terrorism as a military tactic to achieve their goals, and there is no international consensus on the bureaucratic definition of terrorism. Therefore, this list is of organizations that are, or have been in the past, designated as "terrorist organizations" by other notable organizations, including the United Nations and national governments, where the proscription has a significant impact on the group's activities.
