Clairvaux MacKillop College is a Roman Catholic co-educational secondary school located in Upper Mount Gravatt, a suburb in the south side of Brisbane, Queensland, Australia.

In 1971 it was decided that the all-girls Catholic secondary school St Joseph's College be moved from its current location in Holland Park to the site adjoining Clairvaux College and be renamed Mackillop College.

Both schools operated as separate colleges until 1984, with some sharing of classes, teaching staff, and sports facilities.

A decision was made to amalgamate the two colleges and full integration occurred in 1988 with the co-educational school renamed to Clairvaux MacKillop College.

[3] The students are divided into the following 6 houses: The house system was expanded in 1995 and the six houses participate in fund raising for selected charities, vie in three inter-house sporting events annually[4] and come together as a united college for inter-school sport events.
