Ambrose Treacy College (ATC) is an independent Catholic primary, secondary, and high school for boys, located in Indooroopilly, Brisbane, Queensland, Australia.

[3] During these 2 years of military occupation, "the 5 Christian Brothers and 100 boys of the college lived and carried out their school duties in a hotel, 2 houses and a hut at Mount Tamborine".

The Edmund Rice building (containing the main reception and chapel) was built in 1938 to provide additional boarding accommodation for St Joseph's College at Nudgee.

It is listed on the Brisbane Heritage Register as it is an excellent example of Interwar Functionalist architecture with its simple geometric volumes, asymmetrical massing and distinctive Modernist windows.

[12] Since 2013, the number of buildings have increased with multiple blocks of classrooms and facilities being built, catering to the middle and senior school primarily.

[citation needed] As an acknowledgement of its Irish Heritage the four Houses of Ambrose Treacy College are named after the four provinces of Ireland: Connacht (green), Leinster (blue), Munster (red) and Ulster (gold).

Connacht, inspired by the values of Saint Brendan, Leinster, symbolised by the leadership of the Giant, Fionmac Cumhaill, Munster represented by the image of the High King Brian Boru and Ulster by the rebel Cú Chulainn.This system allows for an interactive teaching of Irelands rich history, whilst involving all boys from grades 4 to 12 in regular inter-house and house championship competitions.

The school maintains multiple teams that play Australian rules football, soccer, basketball, tennis, water polo, cricket, volleyball, and swimming, amongst others.
