Koksoak

The Koksoak River (French: rivière Koksoak) is a river in northern Quebec, Canada, the largest river in the Nunavik region. The Inuit village and region's administrative centre Kuujjuaq lies on the shores of the Koksoak, about 50 kilometres (31 mi) south from its mouth.

The name Koksoak is believed to originate from Moravian missionaries who evangelized among the Inuit of the area at the beginning of British rule and incorrectly spelled the Inuktitut word Kuujjuaq, meaning "great river." In the 19th century, the river was also known as Big or South River, taken from South Bay which was the name of Ungava Bay at that time. In 1916, the name Koksoak was officially adopted.

The Koksoak River arises at the confluence of its two main tributaries, the Rivière aux Mélèzes to the west and the Caniapiscau River to the south. The Koksoak River flows for about 80 kilometres (50 mi) in an east-northeasterly direction into Ungava Bay, and passes by the village of Kuujjuaq, from where it flows northwards for about 50 kilometres (31 mi) to the coast.
