The Battle River flows for 570 kilometres (350 mi) and has a total drainage area of 30,300 square kilometres (11,700 sq mi). The mean discharge is 10 m³/s at its mouth.
The river did not gain its current name until relatively recently. When Anthony Henday passed through the region in the 1750s, he did not mention a river with this name. But by 1793 Peter Fidler mentions arriving at the "Battle or Fighting River", likely so named because of the beginning of a period of rivalry between the Iron Confederacy (Cree and Assiniboine) and the Blackfoot Confederacy.
The headwaters of Battle River is Battle Lake in west-central Alberta, east of Winfield. The river meanders through Alberta eastward into Saskatchewan, where it discharges into the North Saskatchewan River at Battleford. Over its course, the river flows through Ponoka and by Hardisty and Fabyan within Alberta. Big Knife Provincial Park is situation on the south bank of the river west of Highway 855, approximately 15 km (9.3 mi) southwest of Forestburg. The Fabyan Trestle Bridge crosses the river.
