Palmyra High School is a four-year comprehensive public high school that serves students in ninth through twelfth grades from Palmyra in Burlington County, in the U.S. state of New Jersey, operating as the lone secondary school of the Palmyra Public Schools. High school classes began shortly after the completion of the Spring Garden Street School in 1895, which is on the National Register of Historic Places.Cooper, et al., Life on the Delaware - A History of Palmyra, New Jersey 1976. With increased enrollment, the school was moved to a former girls school, Berkeley Hall, in 1907, and to its own building in 1909. A large addition was completed in 1922. The 1909 structure was destroyed by fire in 1957, and after a vote that narrowly defeated establishing a regional high school, additions were made to the building in 1958 and 1961.

As of the 2024–25 school year, the school had an enrollment of 385 students and 29.8 classroom teachers (on an FTE basis), for a student–teacher ratio of 12.9:1.
