Joseph Konopka (born June 24, 1976), better known by his self-invented alias Dr. Ch@os (typically spelled Dr. Chaos by the media), is an American citizen who served 16 years of a 20-year prison sentence for arson, vandalism, and possessing chemical weapons. In 2003 in Illinois, he pleaded guilty to chemical weapons possession for storing cyanide in a disused Chicago subway storage room and was sentenced to 13 years.

In 2004, he pleaded guilty to six felony counts of arson and vandalism, as well as trespassing, and was sentenced to 21 years. These convictions were later overturned on a federal appeal. Konopka pleaded guilty again and was sentenced to an additional seven years.
