Junction City is a village in Portage County, Wisconsin, United States.

In 1872 the Wisconsin Central Railroad laid rail west from Stevens Point through forests and swamps, heading toward what would become Marshfield, aiming to eventually reach Lake Superior.

[7]: 312 In 1876 the Stevens Point Journal reported sudden growth at Junction City.

A school and the town hall appeared on what is now Main Street, away from the rail junction.

[7]: 314–315  Timber was still being cut in the surrounding lands, leaving behind fields of stumps, to be sold to farmers who survived by logging in winter.

At times, the plant produced "several tons of the finished paint and paste product per day."

That year's personal property roll counted eight horses in town, twelve cows, five people raising swine, and nine carriages etc, but no automobiles.

Other businesses are scattered further out: the Junction City State Bank, two creameries, two "factories," the school, a store, and several warehouses.

In that year a volunteer fire department was formed, equipped with a cart pulled by hand and chemical pressure tanks.

[7]: 315–316 By 1958 the rail lines still passed through Junction City, but U.S. Route 10 ran through town on Main Street,[11] and trucks and autos were replacing train travel.

The village had added several general stores, filling stations and garages, and a weekly newspaper called the Community Press.

[7]: 282 Around 2012 highway 10 was rerouted north of Junction City, reducing traffic through town.
