Oyster Bay is a hamlet and census-designated place (CDP) within the town of Oyster Bay on the North Shore of Long Island in Nassau County in the state of New York, United States. The hamlet is also the site of a station on the Oyster Bay Branch of the Long Island Rail Road and the eastern termination point of that branch of the railroad.

The hamlet's area was considerably larger before several of its parts incorporated as separate villages. At least six of the 36 villages and hamlets of the Town of Oyster Bay have shores on Oyster Bay Harbor and its inlets, and many of these were previously considered part of the hamlet of Oyster Bay; three of those are now known as Mill Neck, Bayville & Centre Island. The Oyster Bay Post Office (ZIP code 11771) serves portions of the surrounding villages also, including Oyster Bay Cove, Laurel Hollow, Mill Neck, Muttontown, Centre Island, Cove Neck, and Upper Brookville.

The population of the CDP of Oyster Bay as of the 2010 Census was at 6,707.
