The El Dorado Fire was a wildfire that burned 22,744 acres (9,204 ha; 35.538 sq mi) in the San Bernardino and Riverside Counties of California in September to November 2020. It was ignited on September 5 by a pyrotechnic device at a gender reveal party in El Dorado Ranch Park, and quickly spread to the San Gorgonio Wilderness Area of the San Bernardino National Forest. Burning over a 71-day period, the fire destroyed 20 structures and resulted in one firefighter fatality, for which the couple hosting the party were charged with involuntary manslaughter.
