The South Shore (French: Rive-Sud) is the general term for the suburbs of Montreal, Quebec located on the southern shore of the Saint Lawrence River opposite the Island of Montreal.

The South Shore is located within the Quebec administrative region of Montérégie.

However, in 1998, a group of researchers at the Institut national de la recherche scientifique concluded that the South Shore of Montreal consisted of four Regional County Municipalities (RCM).

The entire south shore comprising the urban agglomeration of Longueuil and the Couronne-Sud totals 700,904 inhabitants.

However, at this scale, the proportion of people who commute to Montreal for work declines.
