Harrisville is a hamlet and former village in Lewis County, New York, United States.

In 1815, Joseph Bonaparte, elder brother of Napoleon I and former King of Spain, purchased a tract of land from James Le Ray, part of which became the town of Diana.

[8] Harris constructed a sawmill and gristmill, harnessing the West Branch of the Oswegatchie River for power to operate the mills.

[9] When early settlers discovered that the landlord John LaFarge, from whom La Fargeville, New York, takes its name, had acquired title to Bonaparte's land, they abandoned the area, and Harrisville languished for 20 years.

[10] In 1859, Samuel H. Beach and William R. Dodge built a massive tannery on the east side of the river.

The abundant natural resource of forests and water shaped industrial development and served to attract investors and residents supported by a chair factory, a sash and door factory, and several active lumber dealers.

[12] In addition, carriage makers, blacksmiths, a harness shop, and numerous general merchandise stores and retail service establishments such as barbershops and hotels supported community development.

As a common carrier, the railroad also brought visitors to Lake Bonaparte and other vacation spots in the northern Adirondacks.

During World War I, the company experienced financial difficulty because of unfavorable wood contracts.
