Nanticoke is an unincorporated community and former city located on the western border of Haldimand County, Ontario, Canada.

Nanticoke's residential area is bordered on the west by the Nanticoke Industrial Park, home to the Stelco Lake Erie Works and a number of smaller businesses, including Charles Jones Industrial, ESM, and Air Products.

One of Nanticoke's nearby natural landmarks is Peacock Point, which is composed of modest working class houses.

There are plenty of streams, valleys, and Lake Erie within a short driving distance of Nanticoke.

In 1974, the towns of Port Dover and Waterford, the village of Jarvis, and parts of the townships of Rainham, Townsend, Walpole and Woodhouse were amalgamated to form the city of Nanticoke.
