Battle Creek[1] is a river that begins in the south-eastern region of the Canadian province of Alberta, near the border with Saskatchewan, in the Cypress Hills Interprovincial Park.

Battle Creek begins in the Cypress Hills and Palliser's Triangle region of Alberta, is 203 kilometres (126 mi) long, has a drainage area of 2,600 square kilometres (1,000 sq mi), and flows through Alberta, Saskatchewan, and Montana en route to its mouth at the Milk River.

During the dry months, water can be released from Adams Lake to help prevent Battle Creek from dying up, which allows for irrigation throughout the growing season.

Cypress Lake is an interbasin transfer reservoir as it is the source of the Frenchman River and can re-supply Battle Creek during dry years.

The Battle Creek, along with Lake Diefenbaker, are the only two bodies of water in Saskatchewan that support a reproducing population of rainbow trout.
