Donald J. Trump State Park is a 436-acre (1.8 km2) state park in the towns of Yorktown and Putnam Valley in Westchester County and Putnam County, New York. The park consists of property that was donated to New York State in 2006 by developer Donald Trump. Maintenance of the park was halted in 2010 due to budget constraints, and the park remains largely undeveloped. Most of the buildings have been demolished; only a few foundations and the existing tennis court remain.
