The Santiago Canyon Fire of 1889 was a massive wildfire in California, which burned large parts of Orange County, Riverside County, and San Diego County during the last week of September 1889. Until 2018, it was possibly the single largest wildfire in the recorded history of California, with at least 300,000 acres (1,200 km2) of land burned. In mid-August 2018, the Ranch Fire in the Mendocino Complex Fire surpassed the Santiago Canyon Fire in size.
The Witch Creek Fire, also known as the Witch Fire and the Witch-Guejito–Poomacha Complex Fire, was the second-largest wildfire of the 2007 California wildfire season, and the largest one of the October 2007 California wildfires. Although the Witch Creek Fire was individually smaller than the Zaca Fire of 2007, burning 197,990 acres (801 km2) acres alone, after merging with the Poomacha and McCoy Fires, the Witch–Guejito–Poomacha Complex Fire had a total burn area of 247,800 acres (1,003 km2), surpassing the Zaca Fire to become the largest complex fire of 2007. Initially igniting in Witch Creek Canyon, near Santa Ysabel, the Witch Creek Fire rapidly spread westward, fanned by powerful Santa Ana winds, and consumed large portions of San Diego County. On October 25, the Witch Fire merged with the Poomacha Fire to the north, near Palomar Mountain, before also merging with the smaller McCoy Fire on the next day. The Witch–Poomacha Complex Fire was the last fire of the 2007 October wildfires to be extinguished, with the Poomacha Fire being contained on November 13. During its duration, 80–100 feet-high flames were reported by fire officials in the Witch Fire, and the Witch Fire exhibited the characteristics of a firestorm at its height.
The 2008 California wildfire season was one of the most devastating since the turn of the 21st Century. While only 4,923 fires occurred, about half as many as in 2007, the total area burned far exceeded that of previous years. Throughout the year, 1,593,690 acres (6,449.4 km2) of land were burned.
The Rim Fire was a massive wildfire that started in a remote canyon in Stanislaus National Forest, in California. This portion of the central Sierra Nevada spans Tuolumne and Mariposa counties. The fire started on August 17, 2013, during the 2013 California wildfire season, and grew to be the third-largest wildfire in California's history, having burned 257,314 acres. As of 2018, the Rim Fire was California's fifth-largest modern wildfire. As of 2011, the Rim Fire is the largest wildfire on record in the Sierra Nevada mountain range. The Rim Fire was fully contained on Thursday, October 24, 2013 after a nine-week firefighting battle. Due to a lack of winter rains, some logs smoldered in the interior portion of the fire throughout the winter. More than a year passed before it was declared out on November 4, 2014.
2014 saw several notable wildfires igniting in California, especially during the month of May, when multiple fires were ablaze concurrently in Southern California, and during September, when several massive wildfires were burning in Northern California. In the context of the 2012–13 North American drought, as well as powerful Santa Ana winds, weather conditions were ideal for wildfires. A total of 7,865 wildfires ignited throughout the year, which burned at least 625,540 acres (2,531.5 km2) of land. The wildfires caused a total of 146 injuries and 2 fatalities, in addition to causing at least $204.05 million in damage.
The May 2014 San Diego County wildfires were a swarm of 20 wildfires that erupted during May 2014, in San Diego County, California, during severe Santa Ana Wind conditions, historic drought conditions, and a heat wave. The main event during mid-May was preceded by a precursor fire that ignited on May 5. The Bernardo Fire has been declared accidental, and officials believe the Cocos Fire was intentionally set. The causes of the other fires are still under investigation by multiple agencies, and a joint task force was formed to coordinate the investigations and facilitate communications. Six injuries and one fire-related fatality were reported.
The October 2007 California wildfires, also known as the Fall 2007 California firestorm, were a series of about thirty wildfires that began igniting across Southern California on October 20. At least 1,500 homes were destroyed and approximately 972,147 acres of land was burned from Santa Barbara County to the U.S.–Mexico border, surpassing the October 2003 California wildfires in scope, which were estimated to have burned 800,000 acres (3,200 km2). The wildfires killed a total of 14 people, with nine of them dying directly from the fires; 160 others were injured, including at least 124 firefighters. At their height, the raging fires were visible from space. These fires included the vast majority of the largest and deadliest wildfires of the 2007 California wildfire season. The only wildfire in 2007 that surpassed any of the individual October 2007 fires in size was the Zaca Fire.
The Valley Fire was a wildfire during the 2015 California wildfire season that started on September 12 in Lake County, California.

The October 2017 Northern California wildfires, also known as the Northern California firestorm, North Bay Fires, and the Wine Country Fires were a series of 250 wildfires that started burning across the state of California, United States, beginning in early October. Twenty-one became major fires that burned at least 245,000 acres (99,148 ha). The wildfires broke out throughout Napa, Lake, Sonoma, Mendocino, Butte, and Solano Counties during severe fire weather conditions, effectively leading to a major red flag warning for much of the Northern California area. Pacific Gas and Electric reported that red flag conditions existed in 44 of the 49 counties in its service area. Seventeen separate wildfires were reported at that time. These fires included the Tubbs Fire, the Atlas Fire, Nuns Fire, and others. These wildfires were also the most destructive ones of the 2017 California wildfire season. The October 2017 fires were the costliest group of wildfires on record, causing around $14.5 billion in damages, including $11 billion in insured losses and $1.5 billion in fire suppression costs, surpassing the 1991 Oakland firestorm, which until then had been the single costliest fire on record. In addition, the Northern California fires were predicted to cost the US economy at least $85 billion.
The Thomas Fire was a massive wildfire that affected Ventura and Santa Barbara Counties, and one of multiple wildfires that ignited in southern California in December 2017. It burned approximately 281,893 acres before being fully contained on January 12, 2018, making it the largest wildfire in modern California history at the time, being surpassed by the Ranch Fire, part of the Mendocino Complex, less than a year later in August 2018.

Through the end of August 2018, Cal Fire alone spent $432 million on operations. Overall, the fires cost at least $26 billion in property damage and firefighting costs, with $16.5 billion of the cost alone being property damage from the destructive Camp Fire.
The Camp Fire was the deadliest and most destructive wildfire in California history, and the most expensive natural disaster in the world in 2018 in terms of insured losses, as well as the single-most destructive wildfire recorded in modern times. Named after Camp Creek Road, its place of origin, the fire started on November 8, 2018, in Northern California's Butte County. Ignited by a faulty electric transmission line, the fire originated above several communities and an east wind drove the fire downhill through developed areas. After exhibiting extreme fire spread, fireline intensity, and spotting behaviors through the rural community of Concow, an urban firestorm formed in the foothill town of Paradise. With the arrival of the first winter rainstorm of the season, the fire reached 100 percent containment after seventeen days on November 25, 2018.
