The Associated Catholic Colleges (ACC) is a group of thirteen independent Catholic boys schools in Victoria, Australia. The Association, formed in 1911, and renamed in 1948, provides the basis for interschool sporting and other competitions between member schools.

Christian Brothers College (now known as St Mary's College) was one of eighteen schools to participate in the first Combined Secondary Schools Athletics Championship conducted by the Victorian Amateur Athletic Association (VAAA) on 7 November 1902 at the Melbourne Cricket Ground.^[1] The Adamson Cup, donated by the headmaster of Wesley College and president of the VAAA, was presented to the winning school. Christian Brothers College East Melbourne (now known as Parade College) was the only Catholic College to ever win the cup in 1910.

The history of sporting competition between Catholic Secondary Schools in Melbourne and Victoria, goes back to 1911, when the Secondary Schools' Championship Meeting was first conducted by the School Amateur Athletic Association of Victoria on 3 November at the East Melbourne Cricket Ground.^[2] The colleges that competed in this first competition were the Christian Brothers Colleges of East Melbourne, St Kilda, North Melbourne, South Melbourne, St Patrick's College, Ballarat and Assumption College, Kilmore. This group later became 'The Combined Catholic Schools Association'.^[3] The Association was also known as the Associated Catholic Secondary Schools^[4] prior to it becoming the Associated Catholic Colleges in 1948. Member colleges took part in an annual athletics meeting, football, handball and tennis competitions. As the competition expanded additional Catholic secondary colleges conducted by other male religious orders such as the De La Salle Brothers, Marist Brothers and others also participated in the competition which included cricket by 1928.^[5]

The first swimming carnival for the Associated Catholic Secondary Schools of Victoria was held on 2 March 1932 at the Kew City Baths, with Christian Brothers Colleges of East Melbourne, North Melbourne and St Kilda and De La Salle competing.

In 1940, the Athletics competition was divided into two divisions due to the number of participating colleges.^[6] Division 1: CBC Parade, CBC St Kilda, St Joseph's North Melbourne, De La Salle, St Patrick's Ballarat, St Patrick's Sale and Assumption. Division 2: St Kevin's, St. Bede's, St Monica's Essendon, St Joseph's Geelong and St Patrick's East Melbourne.

In 1951, member colleges were divided into the metropolitan^[7] (CBC North Melbourne, CBC Parade, CBC St Kilda, De La Salle, St Bede's, St Bernard's and St Kevin's) and country^[8] (Assumption, CBC Warrnambool, Marcellin Mt Gambier, Marcellin Camberwell, Marist Bendigo, St Joseph's Geelong, St Patrick's Ballarat and St Patrick's Sale) groups to compete in the athletics championship. The Archbishop's Shield for the Division 1 Athletics Champions was awarded to the new Associated Catholic Country Colleges aggregate winners, and the newly donated Old Collegians Shield was awarded for the city colleges aggregate winners. The final Associated Catholic Country Colleges Athletics carnival was held in 1975.
