Angelica is a town in the middle of Allegany County, New York, United States. The population was 1,411 at the 2000 census. The name Angelica is from Angelica Schuyler Church, Alexander Hamilton's sister-in-law and wife of John Barker Church. There is also a village called Angelica located in this town.
The area was first settled around 1802 at Angelica Village. The Town of Angelica was formed in 1805 from the Town of Leicester in Livingston County, New York, before Allegany County was formed. The town was originally not intended to be named Angelica, and it is suggested that Angelica Church carried on affairs with numerous influential people in the area to ensure its naming. It's also said[who?] that Hamilton himself had a hand in the naming. Angelica is the oldest town in Allegany County. The town hall is housed in the Old Allegany County Courthouse, listed on the National Register of Historic Places in 1972. The Moses Van Campen House was listed in 2004.
According to the United States Census Bureau, the town has a total area of 36.5 square miles (94.5 km²), of which, 36.5 square miles (94.4 km²) of it is land and 0.04 square miles (0.1 km²) of it (0.05%) is water.
