Largest Wildfires in the US in 2025

What this chart shows. The 20 largest wildfires in the United States in 2025, by acres burned. The Dragon Bravo Fire in Arizona was the largest at 145,504 acres, followed by the Lee Fire in Colorado with 137,758 and the Cottonwood Peak Fire in Nevada with 132,604.

How the data is collected. Sizes and causes come from the NICC annual report's list of the 40 largest wildfires, built from SIT/209 situation reports. Of the 20 shown, 13 were started by lightning, one, the Cram Fire in Oregon, by people and 6 have an undetermined cause; the Roundabout and Ptarmigan complexes are groups of fires managed together and listed as one.

Background. The report says Dragon Bravo, in Grand Canyon National Park, became the nation's largest fire of 2025. It adds that the Lee, Cottonwood Peak and Red Canyon fires, which started in August and grew past 100,000 acres, burned in relatively light fuels and did not need extended national firefighting resources. Alaska had 4 of the 20 fires.

Limits. The report also lists the Moldy Fire (72,216 acres) separately, but the WFIGS incident database records it as part of the Roundabout Complex, so it is left out here to avoid counting the same land twice. Sizes differ slightly between sources: WFIGS gives Klikhtentotzna 117,908 acres and Wikipedia gives Gifford 131,614.
