The 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 and in the form of an organisation to succeed the Austrian Camp Community Mauthausen (ÖLM).

In 2000 the ÖLM – the organisation representing the survivors of Mauthausen concentration living in Austria – officially appointed the MKÖ as their successor organisation. The transition was marked by a ceremony in the Austrian Parliament at the invitation of the then-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 there are 18 national organisation which trace their origins back to resistance activities in Mauthausen.
