The Harrison Public School District is a comprehensive public school district serving students in Kindergarten through twelfth grade, located in the municipality of Harrison, in Hudson County, New Jersey.

Harrison is located 12 miles to the west of New York City, and is sandwiched between Newark (the state's largest city) to the west and Jersey City to the east.

The district is one of 31 Abbott Districts statewide.

The district is comprised of four schools: Lincoln Elementary School (Pre-Kindergarten through the 3rd grade), Hamilton Elementary School (4th and 5th grades), Washington Middle School (6th through 8th grades), and Harrison High School (9th through 12th grades).

The Harrison Public School District is participating in the Interdistrict Public School Choice Program. For the 2005-06 school year parents can request to transfer a child from the Washington School, designated by the State of New Jersey as a Category I School, to another school which is not a Category I School. Since there is only one elementary school in Harrison, parents can request a transfer to the Hoboken Public Schools under the Choice program. A transfer request will depend upon the capacity of the selected Hoboken school.

In September 2007, Harrison realigned the grades being housed in each of the school buildings in town. The new Harrison High School located on Hamilton Street between Kingsland and Schuyler Avenues opened to students in grades 9 through 12. As a result, the old Harrison High School building, located on 1 North 5th Street, was renamed as Washington Middle School.

As of 2009, the old Lincoln School Annex located on Hamilton Street between North 2nd and North 3rd Streets, changed its name to Hamilton School. The school now has it own identity.

The construction of a new structure to house Harrison High School began in January, 2005, and was completed in the summer of 2007 in time for the 2007-2008 school year. The new Harrison High School is located at the intersection of Kingsland Avenue and Hamilton Street in the northeastern-most corner of the town on the former site of Clayton Container. A new stadium was constructed along with the school building.

The campus includes a football/soccer field, baseball diamond, softball diamond, running track around the fields, and 3 tennis courts. The building includes thirty general education classrooms and four special education.
