Industrial disasters are mass disasters caused by industrial companies, either by accident, negligence or incompetence.

The worst industrial disaster on record is the Bhopal Disaster in India, in which a leakage of toxic chemicals from a Union Carbide plant killed over 7,000 people, injured many more, and causes the region's human and animal populations severe health problems to the present.

Other disasters can be considered industrial disasters, because their causes are rooted in the products or processes of industry. For example, the Great Chicago Fire of 1871 was severe due to the heavy concentration of lumber industry, wood houses, fuel and other chemicals in a small area.
