The Wantagh State Parkway is a parkway on Long Island, New York that links the Ocean Parkway at Jones Beach State Park with the Northern State Parkway in Westbury. It is unsigned New York State Reference Route 908T.

The parkway is located approximately 30 miles east of Manhattan and 14 miles east of the Nassau-Queens border. It runs north-south providing four lanes worth of traffic north of exit W4 (Southern State Parkway) and six lanes south of exit W4. The parkway starts from the south at Jones Beach (where it meets the Ocean Parkway at a traffic circle), and runs through Wantagh, which is a populated suburb of New York City. As the parkway moves north toward Westbury, it cloverleafs with larger capacity roadways such as Merrick Road, Sunrise Highway, the Southern State Parkway, Hempstead Turnpike, and Old Country Road before ending at the Northern State Parkway.
