Mamaroneck is a town in Westchester County, New York, United States. The population was 29,156 at the 2010 census. There are two villages contained within the town: Larchmont and the Village of Mamaroneck (part of which is located in the adjacent town of Rye). The majority of the town’s land area is not within either village, constituting an unincorporated area, although a majority of the population lives within the villages. Legally, the unincorporated section and the villages constitute the town as a political and governmental subdivision of New York State. The town is led by a town board, composed of five town board members, which includes the Town Supervisor, Nancy Seligson.

Much of the unincorporated section of the town receives its mail via the Larchmont Post Office and thereby has a Larchmont address.

The publication division of Archie Comics is headquartered in Mamaroneck.

The town is home to Walter’s Hot Dog Stand, a Westchester County landmark. In 2010, Walter’s was listed on the National Register of Historic Places.
