Thunder Creek is a river in the Canadian province of Saskatchewan. The watershed of Thunder Creek is within the semi-arid Palliser's Triangle in south-central Saskatchewan. It begins at small, man-made reservoir near Lake Diefenbaker and flows in a south-easterly direction towards the city of Moose Jaw and the Moose Jaw River. The Moose Jaw River is a major tributary of the Qu'Appelle River For most of its course, Thunder Creek follows a valley called the Thunder Creek meltwater channel that was formed over 10,000 years ago near the end of the last ice age.

During the drought of the 1980s, the river, and the marshes and lakes along its course, almost ran dry. To stabilise water levels, a reservoir was built at the head of the river. The reservoir is supplied by pumping in water from nearby Lake Diefenbaker.
