Waterfall is a small residential area that lies north-east of Hillcrest in the province of KwaZulu-Natal, South Africa. Although Waterfall is officially regarded as a separate suburb from Hillcrest, it is often locally regarded as something of an extension of Hillcrest.

Waterfall is situated in the Upper Highway Area of Durban, approximately 33 kilometres (20 mi) north-west of the city and is bordered by Hillcrest to the south-west, Kloof to the south-east and KwaNgcolosi and KwaNqetho to the north.

The main area of Waterfall consists of Waterfall proper and the smaller semi-rural suburbs of Berrel, Crestholme and Crestview which are largely made up of small holdings.

Inanda Road mainly intersects Waterfall connecting the suburb with Hillcrest to the south-west (numbered as the M33) and with Molweni to the north-east. Link Road, also numbered as the M33, connects Waterfall with Kloof to the south-east.
