The Martigny River is a tributary of the Turgeon River, flowing into the Municipality of Eeyou Istchee James Bay (municipality), in Jamésie, in the administrative region from Nord-du-Québec, in Quebec, in Canada. The course of the river crosses the townships of Martigny, Martinière and Lanouillier.
This hydrographic slope is covered by several marsh areas. The surface of the river is usually frozen from early November to mid-May, however, safe ice movement is generally from mid-November to the end of April.
The main hydrographic slopes near the Martigny River are:
- North side: Harricana River, Breynat River, Mannerelle River, Malouin River;
- East side: Harricana River, Samson River (Baie-James);
- South side: Turgeon River, Wawagosic River;
- West side: Turgeon River, Detour River.

- 4.6 kilometres (2.9 mi) Southeast across Lake Martigny (length: 5.7 kilometres (3.5 mi); altitude: 242 metres (794 ft)), up to mouth;
- 8.4 kilometres (5.2 mi) Southeast across Finger Lake (length: 2.5 kilometres (1.6 mi); altitude: 242 metres (794 ft)), up to its mouth;
- 6.9 kilometres (4.3 mi) Southeasterly to mouth[2]
