Smithville is a community in the township of West Lincoln, Niagara Region, Ontario, Canada.

Settlers who wanted their grain ground were required to provide their own motive power by putting their oxen on the tread.

Later, Smith Griffin built a dam and mill on the Twenty Mile Creek, making the treadmill obsolete.

Population:[7] Mother tongue: Patron: Retail establishments in Smithville are congregated amongst two major nodes: the downtown core, and the Village Square Mall.

It has trees and benches, and features the town clock (from the original post offices) mounted on a pedestal.

The council chambers and the largest branch of the municipal library are located in town, as well as the major fire station.

The area north of Townline Road, the bulk of the community, was part of Ward 3, the former Township of South Grimsby.

Regional Road 20, formerly King's Highway 20, goes primarily east-west, connecting Smithville with Niagara Falls and Hamilton.

Regional Road 14 connects Smithville to Grimsby and the Queen Elizabeth Way in the north, and Highway 3 in the south.

The former station (built 1903) is a local landmark, and serves as the headquarters of the West Lincoln Historical Society.
