Bayport-Blue Point High School is a high school in Bayport, New York, United States. It was originally constructed in 1927 as an elementary school and high school for the Hamlet of Bayport. It is part of Bayport-Blue Point Union-Free School District, along with three elementary schools (Academy Street, Blue Point, and Sylvan Avenue) and one middle school (James Wilson Young Middle School).

The school originally consisted of a single unit built in 1927, with numerous additions over the years, one in 1940 and another in 1960.

In March 2003, the Bayport-Blue Point School district passed a bond referendum that gave the high school significant upgrades. During the 2003-2004 school year, a new auditorium was built at the southwest corner of the school, and the music rooms were renovated. During the 2004-2005 school year, another addition was added at the northeast corner of the school incorporating a new front entrance, an enlarged cafeteria, and ten new classrooms. During the 2005-2006 school year, the gymnasium received significant upgrades, which included the addition of a newer but smaller auxiliary gymnasium, new weight rooms, and a secondary gymnasium lobby. The bond, which was completed in time for the 2006-2007 school year, cost $35.5 million, and added approximately 50,000 square feet in additional space.

In November 2015, the district passed another bond worth $30 million, of which $8 million is going into the high school. Among the improvements are the construction of two brand-new turf fields, restoration of the original 1927 building, locker replacement, and curb/masonry restoration.

In 2017, the school was named a National Blue Ribbon School.
