Arnott is an unincorporated community located in Stockton, Portage County, Wisconsin, United States.

In 1872, the Green Bay and Western Railroad laid tracks through a portion of Arnott.

During 1881 and 1882, William Arnott, Joseph Bremmer, and Calvin Richmond canvassed the countryside, raising money to build a railroad depot.

[3] The depot and the settlement around it were named after Arnott, a local farmer who served as chairman of the town of Stockton and the Portage County Board and who was elected to the Wisconsin Legislature in 1876.

Arnott has one tavern, a feed mill, a lawn equipment dealer, and an egg roll factory.
