Pope John XXIII Regional High School is a Roman Catholic high school in Sparta, in Sussex County, in the U.S. state of New Jersey. The school was founded in 1956, originally as Our Lady Of The Lake School and is part of the Roman Catholic Diocese of Paterson. The school name was changed to honor Pope John XXIII after his death in 1963. The school has been accredited by AdvancEd since 2010.

As of the 2023–24 school year, the school had an enrollment of 711 students.

In 2016, grades 5-7 at the Rev. George A. Brown Elementary School were moved into the newly built Pope John XXIII Middle School, which shares its campus with the high school. To do this the schools of Immaculate Conception Regional School (in Franklin), Saint Joseph's Regional School (in Newton) and Saint Michael's Regional School (in Netcong) were all closed and merged into Pope John Middle School.
