New York State Route 101 (NY 101) is a 3.58-mile (5.76 km) long state highway in northwestern Nassau County, New York, in the United States. It runs north–south as Port Washington Boulevard from NY 25A in Flower Hill, west of Roslyn and east of Manhasset, to Astor Lane in Sands Point. It becomes County Route 101 (CR 101) south along Searingtown Road to Shelter Rock Road (CR 8) and becomes Middle Neck Road (CR D55) north of Astor Lane, continuing north and west to a dead end at the Long Island Sound as the unsigned County Route D55 (CR D55).

NY 101 was assigned c. 1931 while the county route continuations were assigned in 1959. CR 101 was initially signed; however, signage for the route was removed in 1973. In the 1960s, a proposal was made to construct an expressway, known as the Western Nassau Expressway. This expressway would have extended from NY 27 to NY 101 and utilized the NY 101 corridor north of NY 25A. The proposal was shelved in the 1970s.
