The Broadback River (French: Rivière Broadback) is a river in northern Quebec, Canada. It drains into Rupert Bay (a smaller bay at the south end of James Bay), just south of the Rupert River and Cree community Waskaganish. The major lake on the river's course is Lake Evans.

The Broadback, together with the Nottaway and Rupert Rivers, was initially considered to be dammed and diverted as part of the James Bay Project. However, in 1972 hydro-electric development began on the more northerly La Grande and Eastmain Rivers, and the NBR Project was shelved. With the decision to divert the Rupert River to the La Grande, it is not likely that the Broadback will be developed in the foreseeable future.

River is a popular canoe-tripping destination.[2]


Since the Broadback River flows relatively close to the northern edge of its basin, most of its major tributaries are left tributaries. Major tributaries in downstream order include:
