The Frye Fire was a wildfire that burned 48,443 acres (19,604 ha) in Graham County, Arizona, United States, from June 7 to September 1, 2017.

The fire was ignited by a lightning strike on Mount Graham, within the Coronado National Forest, and spread rapidly until it was mostly contained on July 12.

Beginning in July 2017, rains from the annual North American monsoon season washed sediments off mountain slopes in the Frye Fire's burn scar.

[6]: 5–6 [5] By June 9, an area of 15–20 acres (6.1–8.1 ha) was on fire, and the flames were spreading in the direction of the Frye Mesa Reservoir.

[12] Beginning on June 18, an enlarged force of over 300 firefighters focused on preventing the Frye Fire from reaching the Mount Graham International Observatory (MGIO).

[16][17] On June 24, the Frye Fire was pushed back from the MGIO and was estimated to be 29 percent contained, but the burned area had grown to 35,569 acres (14,394 ha).

[28] On June 17, the USFS announced that an outbreak of streptococcal pharyngitis (strep throat) had begun among the firefighters assigned to contain the Frye Fire.

[36] They released a report on July 20 that recommended stabilizing soil deprived of understory and the clearing of roads of drainages.

[41][42] Two homes were damaged on July 31 when Ash Creek overflowed and was partially filled in with sediments washed out of the burn scar.

[49] In July 2021, the USFS and Arizona Department of Forestry and Fire Management began to employ inmates from the Fort Grant state prison in a three-year project to restore trails on Mount Graham.
