The Wiese is a river, 57.8 kilometres long,^[1] and a right-hand tributary of the Rhine in southwest Germany and northwest Switzerland.

From its source in Baden-Württemberg in the Southern Black Forest on the mountain of the Feldberg, it flows for a short distance though the county of Breisgau-Hochschwarzwald and then mainly across Lörrach and through numerous settlements including the county town of Lörrach. After crossing the international border, the lower reaches of the river pass through the canton of Basel-Stadt, mainly through the city of Basel and through its district of Kleinbasel before emptying into the Upper Rhine.

The valley of the Wiese, which drains a catchment of 455 square kilometres,^[1] is called the Wiesental or Wiese Valley; it is oriented roughly towards the south-west. Its largest tributary is the Little Wiese (Kleine Wiese) which approaches from the north. The right-hand Rhine tributary of the Wiese and the left-hand Rhine tributaries of the Birsig, which discharges into the Rhine at the Basel port of Schifflände, and the Mühlebach, which flows under the Dreirosen Bridge, are the three biggest Upper Rhine tributaries on Swiss soil.
