Vineland High School is a four-year comprehensive public high school located in Vineland, in Cumberland County, in the U.S. state of New Jersey, serving students in ninth through twelfth grades as part of the Vineland Public Schools. The now reunified school operates from a south campus that had been Vineland Senior High School South (which opened in 1963) and a north campus that was formerly Vineland Senior High School North (opened in 1976). The original high school in Vineland dates back to 1870, and the 1927 Vineland High School structure was added to the National Register of Historic Places on March 3, 1995, and is now used as district offices. The school is accredited until July 2026 and has been accredited by the Middle States Association of Colleges and Schools Commission on Elementary and Secondary Schools since 1936; The school's accreditation status was extended for seven years in Fall 2018.

As of the 2023–24 school year, the school had an enrollment of 2,799 students and 190.0 classroom teachers (on an FTE basis), for a student–teacher ratio of 14.7:1. There were 1,275 students (45.6% of enrollment) eligible for free lunch and 224 (8.0% of students) eligible for reduced-cost lunch. Based on 2021-22 data from the New Jersey Department of Education, it was the ninth-largest high school in the state and one of 29 schools with more than 2,000 students.

Vineland High School had served students from neighboring communities, as part of sending/receiving relationships with the Buena Regional School District (comprised of Buena and Buena Vista Township for grades 10-12), and from Newfield, Pittsgrove Township and Weymouth Township for grades 9-12. With significant overcrowding at the high school and substantial growth in enrollment from students residing in Vineland, the sending districts were informed in November 1968 that they would no longer be accommodated in Vineland and that all sending students would be phased out by the end of the 1973-74 school year.

Buena Regional High School was constructed to serve an estimated 900 students from the Buena Regional, Estell Manor and Weymouth Township districts, with plans to open for the 1972-73 school year. The Pittsgrove Township School District constructed Arthur P. Schalick High School, which opened in September 1976 for 800 township students who had previously been sent to either Bridgeton High School or Vineland High School.

A proposed dress code, that had been slated to take effect for the 2006–07 school year, gave way to controversy and debate among students and parents.

The school was the 264th-ranked public high school in New Jersey out of 339 schools statewide in New Jersey Monthly magazine's September 2014 cover story on the state's "Top Public High Schools", using a new ranking methodology. The school had been ranked 297th in the state of 328 schools in 2012, after being ranked 275th in 2010 out of 322 schools listed. The magazine ranked the school 222nd in 2008 out of 316 schools. The school was ranked 194th in the magazine's September 2006 issue, which surveyed 316 schools across the state.
