United States–Gulf Cooperation Council relations

The United States and the Gulf Cooperation Council have maintained close bilateral, economic, and military relations since the GCC was founded in 1981. This is due to the United States' close relationship with the six-member states of the GCC, Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates. Despite the U.S. not having formal membership in or representation to the GCC, the United States has chaired formal meetings with the GCC and both sides have been brought closer due to mutual hostility with Iran since the Iranian Revolution in 1979 and the Soviet Union over fears of spread of Communism during the Cold War. Both sides worked together in conflicts such as the Soviet–Afghan War, Iran–Iraq War, and the Gulf War.

Following the September 11 attacks, the GCC and the United States alliance grew closer as they began to cooperate further against terrorism and conduct regular direct meetings and summits. With the rise of the Arab Spring and civil wars in Arab nations, friction between member states of the GCC grew, putting the United States in the middle to resolve the issues through diplomacy seen during the Qatar diplomatic crisis from 2017 to 2021. Following the end of the crisis, relations have only grown stronger and closer in mutual opposition against Iran.
