Mauthausen Committee Austria (MKÖ) was founded in 1997 by the Austrian Trade Union Federation and the Conference of Roman-Catholic Bishops in partnership with the Austrian Jewish Community. The organisation was to succeed the Austrian Association of Mauthausen Survivors (ÖLM).

In 2000 the ÖLM – officially appointed the MKÖ as its successor organisation. The transition was marked by a ceremony in the Austrian Parliament at the invitation of President of Parliament Dr. Heinz Fischer, with the pledge to honour and protect the legacy of the concentration camp prisoners.

The ÖLM is one of several organisations representing survivors of Mauthausen concentration camp under the umbrella organisation Comité International de Mauthausen (International Mauthausen Committee – CIM). Today 18 national organisations trace their origins back to resistance activities in Mauthausen.
