Grand Falls (French: Grand-Sault) is a town in northwestern New Brunswick, Canada, on the Saint John River.

The French missionaries, Récollets, visited Great Falls in 1691 and Antoine de Lamothe Cadillac mentioned the presence of a fort in 1693.

In 1763, the region fully passed into British hands and its French population diminished due to the Expulsion of the Acadians.

In 1785, the Acadians in Fredericton and nearby were evicted from their land and in June 1785, a group decided to establish the region of Grand Falls and the rest of Madawaska and this with the agreement of the Maliseet people.

The territorial differences culminated in the Aroostook War in 1838 and Webster–Ashburton Treaty in 1842, gave Grand Falls to the province of New Brunswick.

In 1838, James Brown and George Hayward visited Grand Falls and mentioned the presence of a sawmill owned by John Caldwell staffed by French Canadians and Acadians.

The ring to which this rope was attached can still be found in O.B Davis Park Grand Falls is located in the valley of the Saint John River, south of Madawaska, 55 kilometres southeast of Edmundston, on the Canada–United States border.

The eastern part of the town, located on the left bank of the river is actually in the county of Madawaska, not to be confused with the eponymous region.

Grand Falls has a humid continental climate (Köppen Dfb) with vast seasonal differences and being cold for the latitude.

The town is also a local commercial centre for Victoria County, catering to the surrounding communities of Plaster Rock, Perth Andover, Blue Bell, and New Denmark.

Near this location, you will find the Falls and Gorge Campground, which provides access to the Camel's back, an impressive rock formation.

There are many outdoor activities you can do in Grand Falls such as zip lining by the gorge and waterfalls, kayaking, canoeing, or boating along the Saint John river.

The Grand Falls Public Library began as a small group of readers forming the Literary Club founded by Senator Muriel McQueen Fergusson.

The library was housed in a small building located on Broadway Boulevard where now stands the Dari Delite Ice Cream Store and was once the old Post Office.

In August 1983, the library moved from Broadway Boulevard to the Masonic Hall on the corner of Sheriff and Church Street.
