Rivière-des-Prairies–Pointe-aux-Trembles (French pronunciation: [ʁivjɛʁ de pʁɛʁi pwɛ̃t o tʁɑ̃bl]) is a suburban borough (arrondissement) on the eastern tip of the city of Montreal, Quebec, Canada.

The third district, La Pointe-aux-Prairies, is a typical suburb composed of townhouses, condos and single-family dwellings, which makes it a destination of choice for young families that wish to remain on the island of Montréal.

The Rivière-des-Prairies part of the borough is more multiethnic and known for its high concentration of Italians and Haitians, while the Pointe-aux-Trembles segment is more homogenous and ethnically French-Canadian.

On July 9, 2006, after Italy won the 2006 FIFA World Cup, Maurice Duplessis Boulevard was closed to traffic due to the great number of fans celebrating in the street.

As of the November 5, 2017 Montreal municipal election, the current borough council consists of the following councillors: Federally it's in the ridings of Honoré-Mercier and La Pointe-de-l'Île, and provincially part of LaFontaine and Pointe-aux-Trembles.
