The Stock Exchange Tower (French: Tour de la Bourse) is a 48-storey skyscraper in Montreal, Quebec, Canada.

When completed in 1964, the tower was the tallest building in Canada, a title it held until surpassed by the Toronto-Dominion Centre in 1967.

The original project, conceived during the Expo 67-era economic boom, called for three identical towers arrayed in a triangle.

Its façade, fully renovated in 1995, features a bronze-tinted anodized aluminium curtain wall, forming a strong contrast with the slightly slanted pre-cast concrete columns at the four corners, giving the whole a subtly convex aspect.

It is divided into three roughly equal blocks by mechanical floors whose corners are recessed in an octagonal shape, creating small open-air interstices behind the columns at these levels.
