Deadman River, Brook in Thompson River region, British Columbia, Canada

Deadman River rises in Hoover Lake on the Bonaparte Plateau, south of Bonaparte Lake, and runs south for about 70 kilometres to join the Thompson River near Savona, west of Kamloops Lake. Along the way it passes through Adler, Allie and Vidette lakes, drops over Deadman Falls and receives Joe Ross, Hamilton and Chris creeks.

The river's name dates to 1817, when Pierre Charette of the North West Company was killed by a travelling companion in a quarrel over a campsite. Archibald McDonald of the Hudson's Bay Company mapped it as Chivrette River in 1827. Later maps recorded Dead River, Defeant River and Rivière du Défunt; the name Deadman River was officially adopted on 7 June 1927.

The river's Shuswap name, recorded by George Mercer Dawson as Hai in wohl, means "a circle or detour", describing the loop the water makes. The name Deadman itself comes from the 1817 killing of Pierre Charette of the North West Company by his travelling companion in a quarrel over a campsite. Fur-trade maps rendered it as Rivière du Défunt and Defeant River before Deadman River was officially adopted on 7 June 1927.

The river rises at Hoover Lake on the Bonaparte Plateau and runs south to meet the Thompson River near Savona, west of Kamloops Lake. Its lower course follows the line of the old Hudson's Bay Brigade Trail, so the approach is from the Savona side. Above Deadman Falls the river drops about 100 m in 400 m, and the flow is highest with spring snowmelt.

The lower section formed part of the Hudson's Bay Brigade Trail, a crucial trade route linking Fort Vancouver with the New Caledonia fur district. This historic pathway shows how the river's geography shaped the region's early commercial networks.
