The Trapps Mountain Hamlet Historic District is located on the Shawangunk Ridge in Gardiner, New York, United States. It is a large area that covers the site of a settlement that thrived there from the late 18th to mid-20th centuries. Inhabitants practiced subsistence farming, making it one of the rare such communities in the East to have left any trace remaining. They supplemented that with a variety of other trades, primarily in the forest products industry, with most inhabitants gradually coming to work at nearby mountain resorts in the 20th century. The last resident died in 1956.

The Shawangunk Ridge, also known as the Shawangunk Mountains or The Gunks, is a ridge of bedrock in Ulster County, Sullivan County and Orange County in the state of New York, extending from the northernmost point of the border with New Jersey to the Catskills. The Shawangunk Ridge is a continuation of the long, easternmost section of the Appalachian Mountains; the ridge is known as Kittatinny Mountain in New Jersey, and as Blue Mountain as it continues through Pennsylvania. This ridge constitutes the western border of the Great Appalachian Valley.
