Mount Denson is an unincorporated community in the Canadian province of Nova Scotia, located in West Hants Regional Municipality.

By 1680 Acadian farmers had migrated out of the Port Royal area and began settling the eastern end of the Annapolis Valley including the lands about Mount Denson, then known as Pisiquit.

[4] When the Expulsion of the Acadians began in 1755 the area's male residents were detained at Fort Edward and later in the fall deported along with their families from the province.

After the deportation of the Acadians, Nova Scotia's fine farmlands in the Bay of Fundy region remained empty and in an effort to repopulate the country the British government offered the recently vacated lands in grant to Protestants who wished to move to the colony.

In 1760, Henry Denson acquired for himself 4000 acres in the new township of Falmouth and acting for the government began distributing the remaining tracts of land to New England Planters.
