Blainville (French pronunciation: [blɛ̃vil]) is a suburb of Montreal located on the North Shore in southwestern Quebec, Canada.

The town sits at the foot of the Laurentian Mountains and is located 35 kilometres (22 mi) northwest of downtown Montreal.

In 1792, a disagreement between Seigneur Hertel and Seigneuresse Lamarque resulted in a division of the seigneurial territory along what was then-called the Great Line (present-day Boulevard du Curé-Labelle or Quebec Route 117).

On 14 June 1968, the parish of Sainte-Thérèse-de-Blainville was divided, and Blainville formed its own town consisting of mostly heretofore undeveloped land.

In 2017, the municipality governed 54.62 square kilometres (21.09 sq mi) subdivided into eleven districts, maintained an independent police force with a budget in excess of 14 million CAD and more than 110 staff,[5] a fire department with over 70 firefighters, who since 2016 also serve the neighbouring municipality of Rosemère,[6] a library with three branches, an arena with two rinks, and an aquatic recreation centre.

The largest visible minority groups were Arab (3.6%), Black (3.3%), Latin American (1.7%), Southeast Asian (0.9%), and Chinese (0.9%).

In July 2004, Le Fontainebleau Golf Club hosted John Daly, Vijay Singh, Phil Mickelson and Hank Kuehne.
