Abraham Josias Sluysken (3 December 1736, Deventer - 18 January 1799, The Hague) was the last Governor of the Dutch Cape Colony before British occupation in 1795.
Sluysken was born in the Netherlands, and in 1765 became governor of the Dutch trading colony of Surat on the northwest coast of India.
With his eye on defense in the case of a possible French attack, Sluysken commissioned the construction of a few small forts at Simon's Town in 1794.
The following year, the citizens of Swellendam and Graaff-Reinet revolted and declared their independence from the Cape.
