The Western Hemisphere Institute for Security Cooperation (WHINSEC), formerly known as the School of the Americas, is a United States Department of Defense school located at Fort Moore in Columbus, Georgia, renamed in the 2001 National Defense Authorization Act.

The institute was founded in 1946; by 2000, more than 60,000 Latin American military, law enforcement, and security personnel had attended the school. The school was located in the Panama Canal Zone until its expulsion in 1984. The school is strongly associated with the dirty wars carried out by U.S.-supported military juntas in South America, particularly in the 1970s and 1980s. Many of its alumni served in repressive, undemocratic governments and engaged in human rights abuses, such as torture and enforced disappearances.
