Cow Neck Peninsula

The Cow Neck Peninsula is a peninsula in Nassau County, New York, on the North Shore of Long Island, in the United States.

The Cow Neck Peninsula was named Cow Neck in the 17th century, in large part due to the fact that it served as a common pasture at the time. The Cow Neck Peninsula is famous for its affluence and historic communities, and was famous for its sand mines along Hempstead Harbor throughout the 20th century.

It is believed that 90% of the concrete that built the foundations of New York City came from the Port Washington sand mines, and that over 100 million tons of sand were shipped to Manhattan.

The Cow Neck Peninsula is also known as Manhasset Neck or simply as Cow Neck.

On its west side, the Cow Neck Peninsula is bordered by Manhasset Bay. On its east side, it is bordered by Hempstead Harbor. To the north, it is bordered by the Long Island Sound. The peninsula's southern border is roughly defined as following Northern Boulevard (NY 25A) between Manhasset Bay to the west and Hempstead Harbor to the east.

Some places on the Cow Neck Peninsula – notably in Flower Hill and Manhasset – reach elevations high enough for the skyline of New York City to be seen from ground level.
