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 north of Manhasset, to Astor Lane in Sands Point. It continues south along Searingtown Road to Shelter Rock Road (County Route 8 or CR 8) and north on Middle Neck Road to a dead end at Long Island Sound as the unsigned County Route 101.

NY 101 was assigned c. 1931 while the county route continuations were assigned in 1958. CR 101 was initially signed; however, signage for the route was removed in 1973. In the 1950s and 1960s, a proposal was made to construct a freeway in western Nassau County. The Western Nassau Expressway, as it was known, 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.

CR 101's southern segment begins at an intersection with Shelter Rock Road (CR 8) and Herricks Road near Herricks High School. The route heads eastward as Searingtown Road, passing to the south of the high school and to the north of a small pond. One block east of Herricks Road, CR 101 intersects with Old Searingtown Road, a former alignment of the current CR 101 alignment. At this point, the highway curves to the northeast and passes through a small area of trees nestled amongst a large, residential area bordering Williston Park. Old Searingtown Road rejoins CR 101 at the northern edge of the forested area.
