Cornucopia is an unincorporated census-designated place in the town of Bell in northern Bayfield County, Wisconsin, United States.

It is near a mainland portion of the Apostle Islands National Lakeshore, which features the Mawikwe Bay Sea Caves.

A historical marker at the Cornucopia beach tells of the Tragedy of the Siskiwit, an Ojibwe battle on that site with a band of Meskwaki that lead to several deaths and the kidnapping of a chief's son.

They were not Great Russians but Carpatho-Russians or Rusyns, an ethnic group found in the mountainous borderlands of Poland, Slovakia, Ukraine, and, Romania.

Commercial fishing for lake trout, whitefish, and freshwater herring has traditionally operated out of Cornucopia's harbor.

In 1903, T.J. Stevenson and Albert Wescott, two land speculators from Iowa established a post office and gave the village the name "Cornucopia" for its abundance of resources.

After World War II, Cornucopia's natural environment led tourism to replace logging, farming, and fishing as the dominant industry of the community.

It contains displays of photographs, family histories and historic artifacts and is open seasonally from mid June to early October.

Siskiwit Bay Marina is near the center of Cornucopia, WI where boaters from all over the midwest come to enjoy their summer times.

The event, put on for the benefit of the volunteer fire department and ambulance service, includes a 5K Run, bike ride, fish, brats & corn, parade, flea market and raffles.
