The Weyauwega derailment was a railroad accident that occurred in Weyauwega, Wisconsin, United States, in the early morning hours of March 4, 1996. The derailed train was carrying a large quantity of hazardous material, which immediately caught fire. The fire, which involved the train cars and an adjacent feed mill, burned for more than two weeks after the actual derailment, resulting in the emergency evacuation of 2,300 people for 18 days, including the entire city of Weyauwega, with about 1,700 evacuees.
