The Saint-Laurent (French: Le Saint–Laurent) was a daily passenger train service operated by Via Rail along the St. Lawrence River from Mont-Joli to Montreal and later Quebec City.

The Canadian National Railway historically operated two daily passenger trains between Montreal and Halifax via Mont-Joli, Campbellton, and Moncton: the Ocean and the Scotian.

[1] On October 28, 1979, Via Rail discontinued the Scotian in favor of extending the Atlantic, a former Canadian Pacific train, from Saint John to Halifax.

Timed transfers connected Saint-Laurent passengers with Corridor trains serving Montreal and points south.

Service was discontinued on January 15, 1990, during a round of severe cuts to the Via Rail network overseen by Benoît Bouchard due to the 1989 budget.
