Blackledge-Kearney House, also known as Cornwallis' Headquarters, is located within the Palisades Interstate Park in Alpine, Bergen County, New Jersey, United States. The original, southern portion of the house was probably built in the 1760s, and the northern addition built around 1840. It was added to the National Register of Historic Places on July 24, 1984. Lord Cornwallis was believed to have used the house as a temporary headquarters during his crossing of the Hudson River in 1776, but modern historians dispute this claim.
