Arden, is a hamlet around the town line of Tuxedo and Monroe, New York, in the United States. It is roughly coterminous with the 10910 ZIP Code.
The area was originally known as Greenwood, and was noted for the iron works belonging to Robert and Peter P. Parrott, of Parrott gun fame. The Greenwood Furnace was established in 1810; during the American Civil War, the furnace produced the iron for the famous Parrott Gun, which was built in Cold Spring, New York by the Parrott brothers. The Parrotts built St. John's Episcopal Church in Arden in 1863. By the 1890s, the iron industry in New York was in decline due to the discovery of surface beds of iron in Minnesota.
