Emerson Hill is the name of a hilly area, and the neighborhood upon which the hill is situated, in Staten Island, New York, one of the five boroughs of New York City, USA.

The hill is named for Judge William Emerson--oldest brother of Ralph Waldo Emerson--who lived with his wife, Susan, and children William, Haven and Charles in a long brown shingle house known as The Snuggery. Willie and Haven were tutored in 1843 by Henry David Thoreau, who lived with the Emersons from May through October. It was the only time in his adult life that Thoreau lived anywhere but Concord, Massachusetts.

A highly affluent community, the roads on Emerson Hill are technically private, and several gates are found at approaches to the enclave; since the gates are seldom closed and are not manned by security personnel, however, it does not officially qualify as a gated community.

In 1971, two large mock Tudor homes at the end of Longfellow Avenue served as Casa Corleone for the filming of Francis Ford Coppola's classic movie The Godfather.

Today, Emerson Hill is separated from its northern neighbor Grymes Hill by the Staten Island Expressway.

The equally exclusive neighborhood of Todt Hill — where private roads also exist — borders Emerson Hill on the south.
