Bantry Bay is an affluent suburb of Cape Town in the Western Cape Province, South Africa, situated on the slopes of Lion's Head and overlooking a rocky coastline.

It was originally called Botany Bay after a botanical garden that was planted here for the cultivation of medicinal herbs.

There is a plaque on the seashore that commemorates a visit by Charles Darwin, who made important geological observations here relating to the nature and origin of granite.
