Kleinmond is a small coastal town in the Overberg region of the Western Cape province, South Africa. It is situated inside a UNESCO-declared biosphere about 90 km east of Cape Town between Betty's Bay and Hermanus. The town's name, meaning "small mouth" in Afrikaans, refers to its location at the mouth of the Bot River lagoon. Stone axe heads found in the area indicate that people already lived in the vicinity of nearby Hangklip 20,000 years ago. Information about the area has existed in writing since the seventeenth century.
