Wabasha is named after the Mdewakanton Dakota mixed-blood (with Anishinaabe) chiefs Wapi-sha, or red leaf (wáȟpe šá - leaf red), father (1718–1806), son (1768–1855), and grandson (±1816–1876) of the same name. The second, Wabishaw the son, signed the 1830 USA treaty with the "Confederated Tribes of the Sacs and Foxes; the Medawah-Kanton, Wahpacoota, Wahpeton and Sissetong Bands or Tribes of Sioux; the Omahas, Ioways, Ottoes and Missourias" in Prairie du Chien. The grandson, Wabasha III (±1816–1876), signed the 1851 and 1858 treaties that ceded the southern half of what is now the state of Minnesota to the United States, beginning the removal of his band to the Minnesota River, then removal from Minnesota to Crow Creek Reservation in Dakota Territory, then to the Santee Reservation in Nebraska, where the last chief Wabasha died.

Wabasha was platted in 1854.
