Mariannhill is a cluster of suburbs and townships in eThekwini Municipality in KwaZulu Natal, South Africa.

In 1882, Trappist missionary Father Franz Pfanner established Mariannhill Monastery 16 km west of Durban.

[2] He promoted local development and opened schools, health clinics, craft workshops, printing presses and farms providing work for hundreds of religious workers and others.

[4] Due to its location close to the industrial townships of Pinetown and Durban, Mariannhill has attracted people from around the province of KwaZulu Natal who are seeking employment.

This has led to the development and growth of several townships in Mariannhill: Mpola, Thornwood, Dassenhoek, Tshelimnyama, Mariannridge, KwaMamdekazi, St Wendolins, and others.
