Place Jacques-Cartier (English: Jacques Cartier square) is a square located in Old Montreal, Quebec, Canada. It is an entrance to the Old Port of Montreal.

In 1723, the Château Vaudreuil was built for Philippe de Rigaud, Marquis de Vaudreuil - its formal gardens occupying the space that is now the square. The Chateau burned down in 1803 and it was suggested by The Hon. Jean-Baptiste Durocher and The Hon. Joseph Périnault that the space be transformed into a public square, known as New Market Place. In 1809, Montreal's oldest public monument was raised there, Nelson's Column. In 1847, the square was renamed in honour of Jacques Cartier, the explorer who claimed Canada for France in 1535.

The broad, divided street slopes steeply downhill from Montreal City Hall and rue Notre-Dame to the waterfront and rue de la Commune.

Montreal City Hall, the five-story (French: Hôtel de Ville de Montréal) is the seat of local government in Montreal, Quebec, Canada. It was designed by architects Henri-Maurice Perrault and Alexander Cowper Hutchison, and built between 1872 and 1878 in the Second Empire style. It is located in Old Montreal, between Place Jacques-Cartier and the Champ de Mars, at 275 Notre-Dame Street East.
