John F. Kennedy High School is a public, four-year high school and International Baccalaureate (IB) World School in the city of La Palma, California. Kennedy gets most of its students from the junior high school across the street, Walker Junior High School.

John F. Kennedy High School opened to 1,488 students in the 10th and 11th grades on September 14, 1964. For its first year of operation, there was no senior class. Kenneth MacPherson was Kennedy's first principal. Most buildings were ready except the dressing rooms, the gym, and playing fields. The school was to be named Centralia, in keeping with Board policy to name high schools after an elementary school district in the area; however, the assassination of John F. Kennedy in 1963 prompted a group of patrons to have the school (then under construction) renamed in his honor.^[9]

In the fall of 2011, the administration of Kennedy High School was criticized for its "Gold Card Program," in which students who performed well on the California Standardized Tests the previous year were given special recognition through special planners and ID cards, along with perks and bonuses at local businesses and throughout the school. Nearby Cypress High School had also implemented a similar program, but it did not receive as much media attention. Both schools have since removed or altered the program.^{[10][11][12][13]}

Currently, Kennedy serves around 2,400 students in the 9th through 12th grades. Recent construction has added a quad area, a second practice gym, renovated classrooms, a new library and counseling center, a modular "4th court," as well as an extensive music building, which includes an auditorium, two band rooms, two choir rooms, practice rooms, and a new pool.

Kennedy's sports teams are known as the Fighting Irish (the senior circle looks like a three leaf clover from above). They are a member of the Empire League in CIF's Southern Section. The school's main rival is Cypress High School. The Fighting Irish football team won the CIF-SS Southern Division Championship in 2006, adding to the AAA championship they had won in 1971.^{[14]: 76, 82} In 2017, the boys volleyball team captured their first CIF-SS Div IV championship in program history. It marked the first time in CIF Southern Section history a wild card team successfully captured the CIF title.^[15]
