Arden is a village and art colony in New Castle County, Delaware, in the United States, founded in 1900 as a radical Georgist single-tax community by sculptor Frank Stephens and architect Will Price. The village occupies about 160 acres, with half kept as open land. According to the 2010 Census, the population of the village is 439. In 1973, the entire village was listed on the National Register of Historic Places.
Two neighboring villages of similar size were founded on Georgist principles, Ardentown, in 1922, and Ardencroft, in 1950. In 2003 they were also listed on the NRHP as the Ardens Historic District. Many Ardenites, as the villagers of Arden are called, consider themselves to be "close-knit, nature-loving, liberal, tolerant, free-spirited, artistic, intellectual, even ex-hippie."
