South & Mid Wales Cave Rescue Team (SMWCRT) is a registered charity (No.1016463) which was initially set up in 1946 to support cavers exploring the caves of the Swansea and Neath Valleys. Since then, with the discovery of major cave systems across South Wales, the team's area of responsibility has expanded dramatically to cover all of South & Mid Wales.

The role of the team has also evolved. From being almost an extension of the local caving club in the 1940's and '50s, SMWCRT now responds to a wide range of incidents on behalf of three Police Forces and two Fire Brigades. In recent years, the incidents attended, as well as traditional cave rescues, have included road traffic Incidents, a great number of animal rescues, providing technical support to Mountain Rescue Teams, searching for missing people and providing assistance on the Thailand Cave Rescue in 2018.
