The United States Department of State maintains a list of Foreign Terrorist Organizations (FTO) in accordance with section 219 of the Immigration and Nationality Act of 1965 (INA). Most of the terrorist organizations on the list are Islamist extremist groups; the rest are nationalist/separatist groups, Marxist militant groups, drug cartels, or transnational gangs.
The Department of State, along with the United States Department of the Treasury, also has the authority to designate individuals and entities as subject to counter-terrorism sanctions according to Executive Order 13224. The Treasury's Office of Foreign Assets Control (OFAC) maintains a separate list of such individuals and entities.

Identification of candidates
The Bureau of Counterterrorism and Countering Violent Extremism (CT) of the United States Department of State continually monitors the activities of groups active around the world to identify targets for the "terrorist" designation. When reviewing potential targets, S/CT looks at the actual attacks that a group has carried out, as well as whether the group has engaged in planning and preparations for possible future acts of violence or retains the capability and intent to carry out such acts.
Designation process
Once a target is identified, the Bureau of Counterterrorism and Countering Violent Extremism prepares a detailed "administrative record", which is a compilation of information, typically including both classified and open source information, demonstrating that the statutory criteria for designation have been satisfied. If the Secretary of State, in consultation with the Attorney General and the Secretary of the Treasury, decides to make the designation, the United States Congress is notified of the Secretary's intent to designate the organization and given seven days to review the designation, as the INA requires. Upon the expiration of the seven-day waiting period, notice of the designation is published in the Federal Register, at which point the designation takes effect. An organization designated as an FTO may seek judicial review of the designation in the United States Court of Appeals for the District of Columbia Circuit not later than 30 days after the designation is published in the Federal Register.
Under the Intelligence Reform and Terrorism Prevention Act of 2004, the FTO may file a petition for revocation two years after the designation date (or in the case of redesignated FTOs, its most recent redesignation date) or two years after the determination date on its most recent petition for revocation. In order to provide a basis for revocation, the petitioning FTO must provide evidence that the circumstances forming the basis for the designation are sufficiently different as to warrant revocation. If no such review has been conducted during a five-year period with respect to a designation, then the Secretary of State is required to review the designation to determine whether revocation would be appropriate.
The procedural requirements for designating an organization as an FTO also apply to any redesignation of that organization. The Secretary of State may revoke a designation or redesignation at any time upon a finding that the circumstances that were the basis for the designation or redesignation have changed in such a manner as to warrant revocation, or that the national security of the United States warrants a revocation. The same procedural requirements apply to revocations made by the Secretary of State as apply to designations or redesignations. A designation may also be revoked by an Act of Congress, or set aside by a Court order.
Legal criteria for designation
(Reflecting Amendments to Section 219 of the INA in the 2001 USA PATRIOT Act)
It must be a foreign organization.
The organization must engage in terrorist activity, as defined in section 212 (a)(3)(B) of the INA (8 U.S.C. § 1182(a) (3)(B)),* or terrorism, as defined in section 140(d)(2) of the Foreign Relations Authorization Act, Fiscal Years 1988 and 1989 (22 U.S.C. § 2656f(d) (2)),** or retain the capability and intent to engage in terrorist activity or terrorism.
The organization's terrorist activity or terrorism must threaten the security of U.S. nationals or the national security (national defense, foreign relations, or the economic interests) of the United States.
Legal ramifications of designation
It is unlawful for a person in the United States or subject to the jurisdiction of the United States to knowingly provide "material support or resources" to a designated FTO. (The term "material support or resources" is defined in 18 U.S.C. § 2339A(b) as "currency or monetary instruments or financial securities, financial services, lodging, training, expert advice or assistance, safehouses, false documentation or identification, communications equipment, facilities, weapons, lethal substances, explosives, personnel, transportation, and other physical assets, except medicine or religious materials.")
Representatives and members of a designated FTO, if they are aliens, are inadmissible to and, in certain circumstances, removable from the United States (see 8 U.S.C. §§ 1182 (a)(3)(B)(i)(IV)-(V), 1227 (a)(1)(A)).
Any U.S. financial institution that becomes aware that it has possession of or control over funds in which a designated FTO or its agent has an interest must retain possession of or control over the funds and report the funds to the Office of Foreign Assets Control of the U.S. Department of the Treasury.
Other effects of designation
The U.S. Department of State lists the following items as additional considered beneficial effects of designation:
Supports efforts to curb terrorism financing and to encourage other nations to do the same.
Stigmatizes and isolates designated terrorist organizations internationally.
Deters donations or contributions to and economic transactions with named organizations.
Heightens public awareness and knowledge of terrorist organizations.
Signals to other governments U.S. concern about named organizations.
Official designation of a group as a Foreign Terrorist Organization also triggers more robust means of combat under the Authorization for Use of Military Force act enacted in 2001, which is still in force today.
Groups designated as FTOs
As of September 10, 2026, the following organizations are designated Foreign Terrorist Organizations:
Delisted FTOs
The following groups have been removed from the Department of State's list as of July 2025, most due to having been disbanded and thus being no longer active.
Controversies
The MEK had been designated a "foreign terrorist organization" in 1997 in order to improve relations with Tehran and then president Mohammad Khatami.
In November 2013, the State Department listed the Nigerian terrorist organization Boko Haram as an FTO. In 2014, Republican members of Congress criticized the State Department for not designating the group as an FTO earlier.
In August 2014, the Christian Science Monitor reported that U.S. military was coordinating with Kurdish forces in Iraq, including elements of the PKK, seemingly in violation of the ban on assistance to a designated FTO.
Since 2024, Congressman Joe Wilson has attempted to introduce a bill to designate the Polisario Front, a UN-recognized liberation movement in Western Sahara, as a terrorist group due to its alleged ties with Iran and Hezbollah. These allegations have been described as Moroccan misinformation and disinformation campaign. UN special rapporteurs Ben Saul and George Katrougalos found that the bill is inconsistent with the United States' international human rights law obligations.
