# List of tallest buildings in Quebec

This is a list of the tallest buildings in Quebec that ranks skyscrapers and high-rise buildings in the province of Quebec, Canada, by height. Buildings in five cities are included in this list; Montreal, Quebec City, Gatineau, Longueuil, and Westmount, each having buildings taller than 100 meters. The tallest building by roof height in the province is the 51-storey, 205-metre-tall (673 ft), 1000 de La Gauchetière. However, for international comparisons, spires are included as per the Council on Tall Buildings and Urban Habitat's most widely used height definition for building height and thus the tallest building according to this definition is the 1250 René-Lévesque at 226.5m (199m without its spire).
Municipal regulations forbid any building from exceeding the smallest of the following two conditions: the height of Mount Royal, or 232,5 m (764 ft) above mean sea level or 200m of building height. Above-ground height is further limited in most areas and a minority of the downtown land plots are allowed to contain buildings exceeding 120 metres in height. The maximum limit is currently attained by 1000 de La Gauchetière and 1250 René-Lévesque, the latter of which is shorter, but built on higher ground.
By contrast, Gatineau and Quebec City do not have building height restrictions.

## Tallest buildings

This list ranks buildings in Quebec that stand at least 100 m (328 ft) tall, based on CTBUH height measurement standards. This includes spires and architectural details but does not include antenna masts. An equal sign (=) following a rank indicates the same height between two or more buildings. Freestanding observation and/or telecommunication towers, while not habitable buildings, are included for comparison purposes; however, they are not ranked. One such tower is the Tour de Montréal.
