The German Mine Sweeping Administration (GMSA) was an organisation formed by the Allies from former crews and vessels of the Nazi Germany's Kriegsmarine for the purpose of mine sweeping after the Second World War, predominantly in the North Sea and Baltic Sea, which existed from June 1945 to January 1948.

The GMSA was formed on 21 June 1945 under Allied supervision, specifically that of the Royal Navy, to clear naval mines in the North Sea and Baltic. It was made up of 27,000 former members of the Kriegsmarine on nearly 300 vessels.

The Allied command was well aware of the problem caused for commercial shipping by the over 600,000 naval mines laid in the seas of Western, Northern and Eastern Europe and had asked that the German mine sweeping formations not be dismissed after the surrender in May 1945. For this reason, Vice Admiral Sir Harold Burrough, British Naval Commander-in-Chief, Germany, undersigned the instruction for the GMSA in June 1945. The British Admiralty preferred to risk German sailors rather than their own to do the dangerous work. The GMSA was originally under the command of Commodore H. T. England; below him, as the highest ranking German officer, was Konteradmiral Fritz Krauss, who had been in charge of mine sweeping operations during the war.

The German sailors initially served in their Second World War uniforms, with the German Eagle and the Swastika removed, and under the same rules and regulations as were valid in the Kriegsmarine. The sailors were paid a moderate wage and had the right to take local leave, unlike other German POW's, but service was not voluntary. Still, the daily, dangerous operations and the resulting high esprit de corps lead to increasing uneasiness about the GMSA, especially in the Soviet Union.
