This is a list of designated terrorist groups by national governments, former governments, and inter-governmental organizations, where the proscription has a significant effect on the group's activities. 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 legal definition of terrorism.   Some organisations have multiple wings or components, one or more of which may be designated as terrorist while others are not.
This listing does not include unaffiliated individuals accused of terrorism, which are considered under lone wolf terrorism. This list also excludes groups that might be widely considered terrorist, but who are not officially so designated according to the criteria specified above.
This list is not all inclusive. For more inclusive lists, including people, entities (corporations), and specific vehicles, refer to lists under .

- Decision by EU Council: The council adopts the list. The decision must be unanimous, which means that every state has a veto right.
- Official Publishing: In the EU Official Journal

The law covered any succeeding organizations of the PKP-1930 and the Hukbalahap which includes the CPP-NPA. Being a member of groups covered by the law is considered illegal.
