Thomas Carr College is a Roman Catholic co-educational day school in Tarneit, Victoria, Australia.

It is named after Thomas Joseph Carr, the second Roman Catholic Archbishop of Melbourne.

In 2006, the principal since the College's founding, Paul D'Astoli, was transferred and succeeded by Bruce Runnalls.

Thomas Carr College is a member of the Sports Association of Catholic Co-educational Secondary Schools (SACCSS) since 2019 and a former member of the Association of Co-educational School (ACS) sporting competition from 2003-2018.

The resulting controversy led to widespread bullying awareness, and the state government introduced various reforms.
