New York City was a pre-War city in the United States.
In 2065, a nuclear reactor, struggling to power the population of seventeen million people, went super critical for a period of about five minutes. While there was no explosion, the NYC incident coined the term "hot summer" for a heat-related electrical overload on nuclear systems.
During the war, the city was affected by the nuclear strikes.
New York City is mentioned in the Fallout Bible 0 and also in a Capitol Post article about the disbanding of the United Nations in Fallout 3. It is also mentioned in the Fallout: New Vegas add-on Dead Money, as well as Fallout 4, with the Statue of Liberty making a cameo appearance in the Atomic Command game. New York City is also listed as "gone" along with Washington, Boston and the rest of the East Coast on Captain Wabash's terminal located in the The Nucleus Command Center. A fan was also arrested by the Boston Police Department for standing on an overturned car and holding a defaced t-shirt with "WE BEAT NEW YORK!" written on it.
