The Allison-Lamotte culture was an archaeological culture that inhabited the Wabash River valley in the United States during the later portion of the Woodland period. Flourishing approximately from AD 100 to 600, the culture's sites are common near the modern city of Vincennes, Indiana. First defined in 1963, the culture was originally described as being divided into two phases — Allison and LaMotte — although some later authors have taught a single unified phase.
