The Tinder Fire was a wildfire that burned 16,309 acres (6,600 ha) of the Coconino National Forest in the U.S. state of Arizona during April and May 2018.

The fire was detected by a United States Forest Service (USFS) lookout tower on April 27, 2018, and firefighters began working to contain its spread within the day.

Benefiting from strong winds, low humidity, and high temperatures, the fire grew rapidly over late April, prompting the closure of Arizona State Route 87 and evacuation orders for 1,000 houses in Coconino County.

[14][15] The next day, rain and snow slowed the growth of the fire and allowed firefighters to make progress in containing its spread.

[17][18] The evacuation orders were lifted on May 4, by which time the fire had grown to an area of 15,841 acres (6,411 ha), but was believed to be 79% contained.
