List of Washington wildfires

These are incomplete lists of the major and minor wildfires in Washington state history, along with total costs of the fires for the years starting in 2002. Wildfires are infrequent on the western side of the Cascade Crest, but a regular component of Eastern Washington ecology.

Major Washington wildfires chronologically
This list only includes "major fires" that destroyed over 5000 acre, incurred fatalities or damaged a significant amount of property. Older fires are increasingly underreported. For example, none of the wildfires of 1926-31 and 1943 that together destroyed more than 500,000 acres of the Colville National Forest are included.

Minor Washington wildfires chronologically
List of minor fires, burning over 1,000 acres and under 5,000 acres with no loss of life or significant numbers of structures.

Year-by-year statistics
Wildfire seasons are defined by Washington state law as lasting from April 15 through October 15 of each year, allowing for burn bans and other restrictions to be imposed on state lands by the Washington State Department of Natural Resources during that time. According to a North American Seasonal Fire Assessment and Outlook report issued in June, 2019, the summer months represent peak fire season.
