Notre-Dame-du-Portage (French pronunciation: [nɔtʁ dam dy pɔʁtaʒ]) is a municipality[2] in the Canadian province of Quebec located at the edge of the Saint Lawrence River in the Bas-Saint-Laurent region.

It is part of the Rivière-du-Loup Regional County Municipality and home to the Riviere-du-Loup Golf Club.

The municipality of Notre-Dame-du-Portage was officially created on July 19, 1856, by merging two sections of Rivière-du-Loup and Saint-André.

A small Stations of the Cross given free of charge at the chapel was blessed by Father Michaud on March 10, 1857.

Construction of the current church, in Romanesque art, began in 1859 with two contractors, Charles Bernier of Cap-Saint-Ignace and Philippe Fortin of Montmagny; the cornerstone was blessed on July 21, 1859.
