     The Gulf of Tonkin incident (Vietnamese: Sự kiện Vịnh Bắc Bộ), also known as the USS Maddox incident, was an international confrontation that led to the United States engaging more directly in the Vietnam War. It involved both a proven confrontation on August 2, 1964 and a claim of a second confrontation on August 4, 1964 between ships of North Vietnam and the United States in the waters of the Gulf of Tonkin. The original American report blamed North Vietnam for both incidents, but the Pentagon Papers, the memoirs of Robert McNamara, and NSA publications from 2005, suggest that the dismissal of legitimate concerns regarding the veracity of the second incident by Department of State and other government personnel was used to justify an escalation by the US to a state of war against North Vietnam.

     On Sunday, August 2, 1964, the destroyer USS Maddox, while performing a signals intelligence patrol as part of DESOTO operations, was claimed to have been approached by three North Vietnamese Navy torpedo boats of the 135th Torpedo Squadron. The North Vietnamese boats attacked with torpedoes and machine gun fire. One U.S. aircraft was damaged, three North Vietnamese torpedo boats were damaged, and four North Vietnamese sailors were killed, with six more wounded. There were no U.S. casualties. Maddox was "unscathed except for a single bullet hole from a Vietnamese machine gun round".

     The National Security Agency originally claimed that another sea battle, the Second Gulf of Tonkin incident, occurred on August 4, 1964, but instead evidence was found of "Tonkin ghosts" (false radar images) and not actual North Vietnamese torpedo boats. In the 2003 documentary The Fog of War, the former United States Secretary of Defense Robert S. McNamara admitted that the August 2 USS Maddox attack happened with no Defense Department response, but the August 4 Gulf of Tonkin attack never happened. In 1995, McNamara met with former Vietnam People's Army General Võ Nguyên Giáp to ask what happened on August 4, 1964, in the second Gulf of Tonkin Incident. "Absolutely nothing", Giáp replied. Giáp claimed that the attack had been imaginary.

     The outcome of these two incidents was the passage by US Congress of the Gulf of Tonkin Resolution, which granted US President Lyndon B. Johnson the authority to assist any Southeast Asian country whose government was considered to be jeopardized by "communist aggression". The resolution served as Johnson's legal justification for deploying U.S. conventional forces and the commencement of open warfare against North Vietnam.

     In 2005, an internal National Security Agency historical study was declassified; it concluded that Maddox had engaged the North Vietnamese Navy on August 2, but that there were no North Vietnamese naval vessels present during the incident of August 4
