Gleeson College is a Catholic school secondary school in Golden Grove, South Australia in the northern eastern suburbs of Adelaide, the capital of South Australia. The college is named after the late Emeritus Archbishop of Adelaide, the very Reverend James William Gleeson and the motto "with one heart" derives from his serving for 10 years (1971–1981) on the Pontifical Council Cor Unum (that is "One Heart").
The campus comprises 3 secondary schools, Gleeson, Golden Grove High School (State) and Pedare Christian College (Anglican / Uniting Church) linked by a central common resource area. Year 11 and 12 students are able to study at the other schools. This campus was visited by Federal Labor Leader Kevin Rudd immediately after his announcement of the current Labor education policy of creating shared facilities at close-together state, Catholic, and/or independent schools. This policy may have been encouraged by the success of the Golden Grove Secondary Campus.
