Mount Royal (French: Mont-Royal, officially Town of Mount Royal, French: Ville de Mont-Royal, abbreviated TMR, French: VMR) is an affluent on-island suburban town located on the northwest side of the eponymous Mount Royal, northwest of Downtown Montreal, on the Island of Montreal in southwestern Quebec, Canada. It is completely surrounded by the city of Montreal. The population was 20,953 as of the 2021 Canadian census. In 2008, most of the Town of Mount Royal was designated a National Historic Site of Canada, as a "[remarkable] synthesis of urban renewal movements of the early 20th century, reflecting the influence of the City Beautiful, Garden City and Garden Suburb movements". The town celebrated its 100th anniversary in 2012.

Town of Mount Royal, or TMR, was founded in 1912. It was created at the initiative of the Canadian Northern Railway as a means of generating funds for the tunnel to be built under the mountain, which would connect the railway to downtown Montreal. The town was designed by Frederick Todd, a planner who was heavily influenced by the likes of Sir Ebenezer Howard and incorporated many aspects of the Garden City Movement as well some elements of the earlier City Beautiful movement into his design. The plan was to build a model city at the foot of Mount Royal. The company bought 4,800 acres (1,900 ha) of farmland, and then built a rail tunnel under Mount Royal connecting their land to downtown Montreal. The profits from the venture helped finance the development of Canadian Northern's transcontinental railroad, which eventually became a significant constituent of the Canadian National Railway system. The town was designed by Canadian Northern's chief engineer, Henry Wicksteed, based loosely on Washington, D.C.

The garden city's coat of arms is composed of several significant elements:

• The royal crown, of French origin, is enclosed in the top panel and blazoned with fleurons.
• Two heraldic roses, of English origin, are stylized wild roses with two rows of five petals separated by pointed sepals.
• The stylized mountain refers to the Town's geographic situation at the foot of Mount Royal.
• The outline of the shield ending in a point recalls the shape of the shields of ancient Greece and Rome.
• Inscribed on the scroll beneath the shield, the motto, Regium Donum, means “gift of the king.”
• Town of Mount Royal's official signature includes the coat of arms as well as the Town's name in French and English. The coat of arms has evolved over the years; the current version dates from 1993.

One notable feature of the town is the naming of some of its streets, and also its occasionally idiosyncratic numbering system. Some streets which pass through the town may thus bear two names (in whichever language). For example, Jean Talon Street, a large east–west thoroughfare crossing Montreal for kilometres (miles), goes a few hundred metres (yards) through TMR under the name of Dresden Avenue, only to recover its Montreal name on the other side of the town. This situation has been recently addressed by putting the two names on the street signs. On these few hundred metres (yards), TMR uses a house civic numbering totally different from that of Montreal on either side. This sort of change in the numbering system also occurs on smaller streets shared by both Montreal and TMR (for example, Trenton, Lockhart and Brookfield avenues, where the TMR numbering system decreases from East to West, only to jump from 2 to 2400 on the few metres (yards) of the street that still belong to Montreal.

In the beginning, the Town was a small farming community, known for its melons. The Daoust family farm grew the celebrated Montreal melon, also called the Montreal nutmeg melon. Green-fleshed and uniquely flavourful, the melons weighed up to 9 or 11 kg (20 or 25 lb). So special was the Montreal melon that it was exported to New York, Chicago and Boston, where, in 1921, people paid as much as $1.50 a slice to taste it. Farming was abandoned over the years, with the gradual urbanization of the Town.

On January 1, 2002, as part of the 2002–2006 municipal reorganization of Montreal, it was merged into Montreal and became a borough. However, after a change of government and a 2004 referendum, it was re-constituted as an independent town on January 1, 2006.

Two main thoroughfares, Laird Boulevard and Graham Boulevard, cut across the borough diagonally and meet at Connaught Park, a green space located in the centre. Mount Royal Train Station, a commuter train station on the Exo Deux-Montagnes line is located to the east of this park. This line is now undergoing construction to upgrade it for the new REM network. Trains going through the Mount Royal Tunnel link the station to downtown Montreal in eight minutes. Both boulevards end at Jean Talon Street and close to the highway.

TMR is surrounded on three sides by a highway, a fence and a rail line.

The highway is Metropolitan Boulevard, a major constituent of Autoroute 40. It was built as an elevated highway throughout, except when it passes through TMR (between Sainte Croix Avenue and L'Acadie Boulevard), since the Town council requested that it be built on the ground, in order to separate the town from the industrial area to the north.

A fence runs along the eastern border with Park Extension at L'Acadie Boulevard, a six lane thoroughfare. The stated purpose of the fence is to prevent children and house pets from running into the busy thoroughfare but some have contended that it was built to keep residents of the working-class Park Extension neighbourhood out of the town.

The rail line is the last portion of Canadian Pacific's Adirondack subdivision. It originally ran through the northern part of the district of Côte-des-Neiges. However, when the town became part of Montreal on Jan 1, 2002, the part of Côte-des-Neiges north of rail line was incorporated into the Mount Royal borough. When the town demerged on Jan 1, 2006 this part, known as Glenmount, reverted to Côte-des-Neiges.

According to the Office québécois de la langue française, Mont-Royal has been officially recognized as a bilingual municipality since 2005-11-02.

In the 2021 Census of Population conducted by Statistics Canada, Mont-Royal had a population of 20,953 living in 7,732 of its 8,192 total private dwellings, a change of 3.3% from its 2016 population of 20,276. With a land area of 7.55 km (2.92 sq mi), it had a population density of 2,775.2/km (7,187.8/sq mi) in 2021.
