One of the New York City sites is also a national monument, and there are two more national monuments in New York City. In New York state, there are 276 National Historic Landmarks (NHLs), the most of any state.

As of 2026, New York State is home to four official National Monuments, all of which are located within the New York City metropolitan area. These sites are the African Burial Ground National Monument (the oldest and largest excavated burial ground in North America for enslaved and free Africans), Castle Clinton National Monument (a circular fort that served as the first U.S. immigration station), Governors Island National Monument (a former military post that played a key role in harbor defense), and Stonewall National Monument (the first U.S. national monument dedicated to LGBTQ+ rights). While New York has dozens of "National Historic Sites," "National Memorials," and "National Historic Landmarks" (it holds the record for the most NHLs of any state at 276), the "National Monument" designation is a specific title granted by the President or Congress for the protection of significant natural, historical, or cultural resources. These four monuments are managed by the National Park Service and serve as vital windows into the diverse and often complex layers of American history, from colonial-era struggles to modern-day civil rights movements.
