Robben Island is an island in Table Bay, 6.9 kilometres (4.3 mi) west of the coast of Bloubergstrand, north of Cape Town, South Africa. It takes its name from the Dutch word for seals (robben), hence the Dutch/Afrikaans name Robbeneiland, which translates to Seal(s) Island.

Section 27 of the National Heritage Resources Act (NHRA) of South Africa provides for places of historic or cultural importance to be designated national heritage sites. This came into effect with the introduction of the Act on 1 April 2000, when all former national monuments declared by the former National Monuments Council and its predecessors became provincial heritage sites as provided for in Section 58 of the Act.
