Hamilton Grange National Memorial is a historic house museum within St. Nicholas Park in the Hamilton Heights neighborhood of Manhattan in New York City. Operated by the National Park Service (NPS), the structure was the only home ever owned by the U.S. founding father Alexander Hamilton. The house contains exhibits for visitors, as well as various rooms with restored 19th-century interiors. Originally located near present-day 143rd Street, the house was moved in 1889 to 287 Convent Avenue before being relocated again in 2008 to St. Nicholas Park. The structure is a New York City designated landmark and a United States national memorial, and it is listed on the National Register of Historic Places.
