Notre-Dame Basilica (French: Basilique Notre-Dame de Montréal) is a basilica in the historic district of Old Montreal, in Montreal, Quebec, Canada. The church is located at 110 Notre-Dame Street West, at the corner of Saint Sulpice Street. It is located next to the Saint-Sulpice Seminary and faces the Place d'Armes square.

The interior of the church is amongst the most dramatic in the world and regarded as a masterpiece of Gothic Revival architecture. The vaults are coloured deep blue and decorated with golden stars, and the rest of the sanctuary is decorated in blues, azures, reds, purples, silver, and gold. It is filled with hundreds of intricate wooden carvings and several religious statues. Unusual for a church, the stained glass windows along the walls of the sanctuary do not depict biblical scenes, but rather scenes from the religious history of Montreal. It also has a Casavant Frères pipe organ, dated 1891, which comprises four keyboards, 92 stops using electropneumatic action and an adjustable combination system, 7000 individual pipes and a pedal board.

In 1657, the Roman Catholic Sulpician syndicate arrived in Ville-Marie, now known as Montreal; six years later the seigneury of the island was vested in them. They ruled until 1840. The parish they founded was dedicated to the Holy Name of Mary, and the parish church of Notre-Dame was built on the site in 1672.

François Baillairgé, an architect, designed the interior decoration and choir 1785-95; facade & vault decoration, 1818.

The church served as the first cathedral of the Diocese of Montreal from 1821 to 1822.

By 1824 the congregation had completely outgrown the church, and James O'Donnell, an Irish-American Anglican from New York City, was commissioned to design the new building. O'Donnell was a proponent of the Gothic Revival architectural movement, and designed the church as such. He is the only person buried in the church's crypt. O'Donnell converted to Roman Catholicism on his deathbed perhaps due to the realization that he might not be allowed to be buried in his church.

The main construction work took place between 1824 and 1829. The cornerstone was laid at Place d'Armes on September 1, 1824. The sanctuary was finished in 1830, and the first tower in 1841, the second in 1843. On its completion, the church was the largest in North America. It remained the largest in North America for over fifty years. A new pipe organ was built in 1858 by Samuel Russell Warren.

The interior took much longer, and Victor Bourgeau, who also worked on Montreal's Mary, Queen of the World Cathedral, worked on it from 1872 to 1879. Stonemason John Redpath was a major participant in the construction of the Basilica.

Because of the splendour and grand scale of the church, a more intimate chapel, Chapelle du Sacré-Cœur (Chapel of the Sacred Heart), was built behind it, along with some offices and a sacristy. It was completed in 1888. In 1886 Casavant Frères began building a new 32-foot pipe organ at the church, completing it in 1891. It was notably the first organ with adjustable-combination pedals to be operated by electricity.
