St Peter's Catholic College is an independent Roman Catholic co-educational secondary day school, located in the Central Coast suburb of Tuggerah, one hour north of Sydney, New South Wales, Australia.

Located in the Roman Catholic Diocese of Broken Bay, the college currently has 1,050 students.

[3] St Peter's Catholic College is within the region of Tuggerah, which according to Aboriginal tradition means savannah, and marshy grassland is evident on the site.

In the beginning, Mater Dei College was built to operate as a Year 7-10 campus for the Catholic community.

This was accompanied in 1987 by the progression of a senior campus known as Corpus Christi College.
