Mamaroneck ( -marr-Ə-nek) 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, Jaine Elkind Eney.

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


According to the United States Census Bureau, the town has a total area of 14.0 square miles (36 km2), of which 6.6 square miles (17 km2) is land and 7.4 square miles (19 km2), or 52.85%, is water. The unincorporated area of the town measures 5.17 square miles (13.4 km2).


The area that is now the town in Mamaroneck was purchased from Native American Chief Wappaquewam and his brother Manhatahan by an Englishman named John Richbell in 1661. During the American Revolutionary War in 1776, the British loyalist William Lounsbury was attacked and killed by a group of revolutionaries led by John Flood. Several other skirmishes occurred that year between loyalists and revolutionaries.

The New York Legislature created Mamaroneck as a town on March 7, 1788. The Town of Mamaroneck is divided into three parts: the Village of Larchmont, an unincorporated area, and the Village of Mamaroneck, the rest of that village being in the town of Rye. This three-part division occurred in the 1890s to meet the growing demand for municipal services that the town could not provide. By definition at the time, a town could only provide basic government functions such as organizing and supervising elections, administering judicial functions, and constructing and maintaining highways.

During the 1890s, parts of the town of Mamaroneck that were situated closest to the water thrived. Larchmont Manor, with its beaches along Long Island Sound, had become well known as a summer resort for families from New York City, and people were beginning to live there year-round. A large part of the town's population lived northeast of the Manor near Mamaroneck Harbor, the commercial center of town, where fishing, shipping, and manufacturing could be found. As the population of these two areas expanded, the residents soon found the need for adequate water supply, sewage disposal, garbage collection, sidewalks, and improved street lighting, police and fire protection.

In 1891, residents of Larchmont Manor obtained a charter from the Legislature under which they incorporated their section of town into a village. Four years later, residents of the most developed and populated sections of the towns of Mamaroneck and Rye voted to incorporate as the Village of Mamaroneck. The Mamaroneck River serves as the boundary separating the towns of Mamaroneck and Rye. While residents of the two villages were now able to receive municipal services, not enough people resided in the unincorporated remainder of the town of Mamaroneck to be included in either village. After World War I, the unincorporated section of the town grew sufficiently that the State Legislature granted the town government the local powers to provide local services it had previously granted to the villages by charter.

In 1921, the course at Winged Foot Golf Club was constructed and opened in June 1923. The golf club has been host to a number of professional tournaments, including the 1997 PGA Championship and the 1929, 1959, 1974, 1984 and 2006 U.S. Open.

The Town of Mamaroneck introduced New York's first vegetable-oil-powered garbage truck in 2008.
