Hempstead Bay is a bay on the coast of New York in the United States.

Hempstead Harbor is a bay in Long Island Sound, between the towns of Oyster Bay on the east and North Hempstead on the west, in Nassau County, Long Island, New York. It is sometimes called Roslyn Harbor.

Hempstead Harbor Park is a recreational beach park owned by the Town of North Hempstead, on the west shore of the harbor in Port Washington. It lies immediately west and north of Bar Beach. A fireworks display takes place there every Memorial Day.

The proposed United States Navy seaplane tender USS Hempstead (AVP-43) was named for Hempstead Bay, but the contract for the ship's construction was cancelled in 1943 before construction began.
