Komatipoort is a town situated at the confluence of the Crocodile and Komati Rivers in Mpumalanga province, South Africa.

It is one of the hottest towns in South Africa where temperatures can reach almost 48 °C (47.7 °C (117.9 °F) on 12 December 1944) in the height of summer, but also with a perfect winter climate around 24 °C (75 °F).

In the 1890s Komatipoort was a wild and uproarious construction camp for the railway being built from Lourenco Marques (modern Maputo).

Komatipoort was the last stop in the South African Republic (ZAR) Pretoria - Delagoa Bay Line constructed by the Netherlands-South African Railway Company (NZASM) with the first train crossing the border at Komatipoort from the ZAR to Portuguese East Africa on 1 July 1891 after the completion of the rail bridge over the Komati River.

They were a bunch of mercenaries and bushwhackers and were recruited by the British in order to fight Boer guerrillas in the bushveld.
