IKUWA – Internationaler Kongreß für Unterwasserarchäologie – is a global network of cooperating bodies that organises congresses focused on underwater archaeology to raise awareness of the importance of underwater cultural heritage and to create an international regulatory framework for its protection.

The congresses are organised under the patronage of UNESCO and the 2001 Convention on the Protection of the Underwater Cultural Heritage.
