The Leusden was an 18th‐century Dutch West Indies Company (WIC) slave ship that foundered on the coast of Suriname, in the entrance of the Maroni River, on the 1st of January 1738. She was on passage from Africa with a cargo of captives when she ran aground.

The actions of the vessel crew changed the incident from simple vessel grounding into the greatest single loss of life in the history of the Dutch slave trade, 664 of the 680 captives on board lost their lives (Balai, 2012). The emotive story of the loss of the Leusden was rediscovered by Dr Leo Balai during his PhD research at the University of Amsterdam in 2009‐2011 and has become the focus of further research and archaeological reconnaissance.
