Pointe-du-Lac, Administrative sector in Trois-Rivières, Canada.

Pointe-du-Lac is a sector of Trois-Rivières on a sandy point at the northeastern end of Lac Saint-Pierre, about 13 km west of the city centre. It is reached by Autoroute Félix-Leclerc and includes the church La Visitation-de-la-Sainte-Vierge, the seigneurial mill of Tonnancour and the manoir seigneurial of 1737, now the presbytery.

The seigneury of the "terre de la Pointe du lac St-Pierre" was granted in 1656 by Trois-Rivières governor Pierre Boucher to his son-in-law Étienne Seigneuret and Jean Sauvaget. In 1734 the seigneury passed to René Godefroy de Tonnancour, and the manoir was built in 1737. The parish was canonically erected on 20 September 1832, and the municipality was created on 1 July 1845, annexed to Trois-Rivières on 1 January 2002.

The parish was called La Visitation-de-la-Pointe-du-Lac from 1722, a name recalling the Visitation of the Virgin Mary to Elizabeth. Since 2018 the parish has been Notre-Dame-de-l'Alliance, while the church keeps the name La Visitation-de-la-Sainte-Vierge. The church site also holds a calvary, a charnel house, a cemetery, an enclosure and a monument.

Pointe-du-Lac lies about 13 km west of Trois-Rivières city centre on a sandy point at the north-east end of Lac Saint-Pierre, reached via Autoroute Félix-Leclerc. The sector's church site groups a calvary, a charnel house, a cemetery, an enclosure, a monument and the presbytery, which is the 1737 seigneurial manor restored in 1913. The Pointe-du-Lac wildlife refuge and the Marcel-Léger ecological reserve protect the wetlands along the lakeshore.

The seigneurial mill of Tonnancour was built in 1721, not 1765, and was restored in the 1970s. It stands as one of the last watermills still in existence in Canada, and its survival is tied to local efforts to save it from demolition.
