Helena is an unincorporated community in the town of Arena in Iowa County, Wisconsin, United States.

The buildings of Helena played a key role in the Black Hawk War of 1832, despite being abandoned at the time.

The first village of Helena was staked out by Henry Dodge as a river port convenient to recently discovered lead deposits around Dodgeville, Blue Mounds, and Mineral Point.

[2] In 1831 Daniel Whitney, an entrepreneur from Green Bay, Wisconsin, formed a company to build a shot tower on a nearby bluff.

To follow them the U.S. army under the command of Henry Atkinson marched 15 miles (24 km) and arrived in Helena on July 26, 1832.
