The Chenal des Grands Voiliers (French pronunciation: [ʃənal de ɡʁɑ̃ vwalje], channel of tall sailships) is a channel of the St. Lawrence River, between Île d'Orléans and the south shore of Quebec, in the province of Quebec, in Canada.

Opposite, on the south shore of Quebec, the channel begins between Gilmour Cove and Pointe De La Martinière.

The course of the Île d'Orléans channel passes under the Hydro-Québec high-voltage lines, which span the river.

This current toponymic designation was awarded in April 1984 by the Commission de toponymie du Québec when the tall ships came to Quebec.
