The Mendocino Complex Fire was a large complex of wildfires that burned in northern California for more than three months in 2018. It consisted of two wildfires, the River Fire and Ranch Fire, which burned in Mendocino, Lake, Colusa, and Glenn Counties in the U.S. State of California, with the Ranch Fire being California's single-largest recorded wildfire at the time until the Dixie Fire in 2021. The Ranch Fire burned eight miles northeast of Ukiah, and the River Fire burned six miles north of Hopland, to the south of the larger Ranch Fire. First reported on July 27, 2018, both fires burned a combined total of 459,123 acres (1,858 km2), before they were collectively 100% contained on September 18, though hotspots persisted until the complex was fully brought under control on January 4, 2019. The Ranch Fire alone burned 410,203 acres (1,660 km2), making it the largest wildfire in modern California history at the time until the August Complex fire that occurred in 2020. The Ranch Fire also surpassed the size of the 315,577-acre Rush Fire, which burned across California and Nevada, as well as the Santiago Canyon Fire of 1889, which was previously believed to have been California's all-time largest wildfire. It also included the Redwood Valley Fire that claimed 8 lives.
The August Complex was a massive wildfire that burned in the Coast Range of Northern California, in Glenn, Lake, Mendocino, Tehama, Trinity, and Shasta Counties.

On September 9, the Doe Fire, the main fire of the August Complex, surpassed the 2018 Mendocino Complex to become both the single-largest wildfire and the largest fire complex in recorded California history. On September 10, the combined Doe Fire also merged with the Elkhorn Fire and the Hopkins Fire, growing substantially in size. By the time it was extinguished on November 12, the August Complex fire had burned a total of 1,032,648 acres (417,898 ha), or 1,614 square miles (4,180 km2), about 1% of California's 100 million acres of land, an area larger than the state of Rhode Island.

The 1992 Fountain Fire was a large and destructive wildfire in Shasta County, California. After igniting on August 20 in an act of probable but unattributed arson, the fire was driven by strong winds, outpacing firefighters for two days while exhibiting extreme fire behavior such as long-range spotting, crown fire runs, and pyrocumulonimbus clouds that generated dry lightning. The fire consumed 63,960 acres (25,880 ha) and destroyed hundreds of homes, primarily in the communities of Round Mountain and Montgomery Creek along the State Route 299 corridor. In 1992, the Fountain Fire was the third most destructive wildfire in California's recorded history, though it no longer features among the top 20 most destructive California wildfires. At a suppression cost of more than $22 million, it was then the most expensive fire to contain, but has since been surpassed in that respect.

The 2012 Reading Fire was a large wildfire in Lassen Volcanic National Park and the Lassen National Forest in Northern California.
