The Stone Harbor School District is a community public school district that serves students in kindergarten through eighth grade from Stone Harbor, in Cape May County, in the U.S. state of New Jersey.

As of the 2022–23 school year, the district, comprised of one school, had an enrollment of 86 students and 9.4 classroom teachers (on an FTE basis), for a student–teacher ratio of 9.2:1. In the 2016–17 school year, Stone Harbor had the 4th-smallest enrollment of any school district in the state, with 75 students.

Starting with the 2011-12 school year, in an agreement with the Avalon School District, public school students in grades K-4 from both communities attend school in Stone Harbor while all students in grades 5-8 attend school in Avalon.

Students in public school for ninth through twelfth grades attend Middle Township High School in Cape May Court House, as part of a sending/receiving relationship with the Middle Township Public Schools, together with students from Avalon, Dennis Township and Woodbine. As of the 2018–19 school year, the high school had an enrollment of 767 students and 64.6 classroom teachers (on an FTE basis), for a student–teacher ratio of 11.9:1.

The district is classified by the New Jersey Department of Education as being in District Factor Group "FG", the fourth-highest of eight groupings. District Factor Groups organize districts statewide to allow comparison by common socioeconomic characteristics of the local districts. From lowest socioeconomic status to highest, the categories are A, B, CD, DE, FG, GH, I and J.

The Avalon and Stone Harbor school districts operate like a single school district even though they are legally two separate districts; they can move teachers between the two schools. In terms of their student populations both districts having among the lowest numbers in New Jersey. As of 2013 both school districts have a single school bus. The property tax rates are 5 cents per $100 of assessed value, relatively low in the state, as the two districts have ample taxable territory of summer houses.

The student sharing agreement means the Avalon and Stone Harbor districts retain foreign language and extracurricular programs they would not otherwise have.

Stone Harbor School had a student body of 99 students in the 2018–19 school year.

In 2016 the school had 70 students. About 40% of the combined Avalon and Stone Harbor students were from out of district and paid tuition, with many coming from the Cape May Courthouse area.

Core members of the district's administration are:

• Stacey LaRocca Tracy, superintendent
• Linda Fiori, business administrator and board secretary

The district's board of education, composed of five members, sets policy and oversees the fiscal and educational operation of the district through its administration. As a Type II school district, the board's trustees are elected directly by voters to serve three-year terms of office on a staggered basis, with one or two seats up for election each year held (since 2012) as part of the November general election. The board appoints a superintendent to oversee the district's day-to-day operations and a business administrator to supervise the business functions of the district. An additional representative is appointed by the Avalon district to represent its interests on the Stone Harbor board.
