Germiston is a city in the East Rand of Gauteng in South Africa.
It was established in the early days of the gold rush when two prospectors, John Jack from the farm of Germiston near Glasgow and August Simmer from Vacha in Germany, struck paydirt on the farm of Elandsfontein. Both men made fortunes and the town sprung up next to the mine. In 1921 the world's largest gold refinery, the Rand
Refinery, was established at Germiston.
Germiston is now part of the Ekurhuleni Metropolitan Municipality which includes much of the East Rand, and is also considered part of Greater Johannesburg.
