The New York City Landmarks Preservation Commission (LPC), formed in 1965, is the New York City governmental commission that administers the city's Landmarks Preservation Law. Since its founding, it has designated over a thousand landmarks, classified into four categories: individual landmarks, interior landmarks, scenic landmarks, and historic districts.

The New York City borough of Manhattan contains a high concentration of designated landmarks, interior landmarks and historic districts. The section of Manhattan below 14th Street is referred to as Lower Manhattan and contains over a hundred landmarks. Some of these are also National Historic Landmark (NHL) sites, and NHL status is noted where known.
