Roberval (French pronunciation: [ʁɔbɛʁval]) is a city on the south-western shore of Lac Saint-Jean in the Le Domaine-du-Roy Regional County Municipality of Quebec, Canada.

With a population of 9,840 in the Canada 2021 Census, it is the fourth largest city on this lake after Alma, Dolbeau-Mistassini and Saint-Félicien.

In their newly renovated arena, Roberval hosted an NHL preseason game between the Montreal Canadiens and the Buffalo Sabres on September 23, 2008.

Roberval is the home of the Traversée internationale du lac St-Jean, an annual swimming competition held since 1955.

The settlement, the oldest village on the shores of Lake Saint-Jean, was first known as Notre-Dame-du-Lac-Saint-Jean, named after the parish founded in 1854.

It experienced rapid growth in the 1880s when Horace Jansen Beemer, an American entrepreneur from Philadelphia, came to Roberval.

He also built a tourist complex in Roberval in 1898, centred on fishing for landlocked salmon and organized excursions to the Grande Décharge (outlet of Lake Saint-Jean).

A fire destroyed the Grand Hotel Roberval in 1908, putting an abrupt end to luxury tourism in the Lake Saint-Jean area.

Due to seasonal lag and influence from the nearby lake, September is well above the subarctic threshold as the fourth warmest month.
