Ireland is an unincorporated community in Madison Township, Dubois County, in the U.S. state of Indiana.

[1] The town was founded on land purchased from the United States government by John Stewart, a native of Ireland, on December 23, 1816.

The town was once intended to be called American City, but changed to Ireland when the name was not approved by the post office department.

Ireland is located 4 miles west of downtown Jasper on State Road 56 in the northeast portion of Madison Township.

Besides the valley caused by the Alder Creek, the area around Ireland is a mostly flat plain that can stretch for miles at certain points.
