List of the largest, most destructive, and deadliest Colorado wildfires that have occurred in modern history.
During the severe 2002 Colorado wildfire season that burned nearly 360,000 acres, the Hayman Fire became the largest wildfire in Colorado state history and held that title for nearly 20 years until the Pine Gulch Fire surpassed it in August 2020. The Cameron Peak Fire became the largest wildfire in Colorado history seven weeks later, and ended up burning a total of 208,913 acres.
The 2012 Colorado forest fires broke the record for most destructive fire twice and led to declaration of a federal disaster area in June 2012. The 2013 Colorado forest fires, fueled by high heat and winds again broke the record for the most destructive and included what was the second largest fire (by area) in Colorado history until being surpassed by several fires in 2020. With multiple record-breaking fires, the 2020 Colorado wildfire season became the largest in the state's history after burning 665,454 acres (269,300 ha).
