'''Route 204''' is a two-lane east–west highway on the south shore of the Saint Lawrence River in Quebec. It is one of the longest secondary highways in the province. Its goes from in Saint-Jean-Port-Joli, at the junction of Route 132, in the east, to Lac-Mégantic, at the junction of Route 161, in the west. Although it is numbered as an east–west highway, the road follows a north–south course from Saint-Jean-Port-Joli to Saint-Pamphile, where it then mostly follows a southwest–northeast course until Saint-Georges. There, it crosses the Chaudière River and then follows it in a north–south course until its source, in Lake Mégantic, in Lac-Mégantic.
