St John Bosco College is an independent systemic Roman Catholic co-educational secondary day school, located in Engadine, a southern suburb of Sydney, New South Wales, Australia.

The college was founded in 1978 under the name St John Bosco High School.

The school was built after many years of planning and effort by the Parish Priest, John Briffa SDB, and a group of parishioners.

Student numbers began to decline in the early 1990s as parents sought a continuous and unbroken secondary education for their sons and daughters.

The school's name was changed to St John Bosco College in 1998 when the first Year 11 students were enrolled.
