Wildfires can happen in many places in the United States, especially during droughts, but are most common in the Western United States and Florida. They may be triggered naturally, most commonly by lightning, or by human activity like unextinguished smoking materials, faulty electrical equipment, overheating automobiles, or arson.

The catastrophic Camp Fire alone killed at least 85 people, destroyed 18,804 buildings and caused $16.5 billion in property damage, while overall the fires resulted in at least $26.347 billion in property damage and firefighting costs, including $25.4 billion in property damage and $947 million in fire suppression costs.
The Boxcar Fire was a wildfire one mile southeast of Maupin, Oregon in the United States. The fire started on June 21, 2018 due to a lightning strike and subsequently burned 100,207 acres (406 km2) due to dry, windy conditions in Central Oregon. The fire was one of 70 wildfires started in Oregon due to lightning strikes over a two-day period. The Boxcar Fire was the largest out of three major fires burning in the region, which included the Jack Knife Fire and South Junction Fire. The fire was contained in late June.
The Tripod Complex Fire was a wildfire which burned in north-central Washington state in 2006. The complex consisted of two wildfire complexes which later merged into a single fire: the Spur Peak Fire and the Tripod Fire. Both were caused by lightning strikes.

The 2020 California wildfire season, part of the 2020 Western United States wildfire season, was a record-setting year of wildfires in California. By the end of the year, 9,917 fires had burned 4,397,809 acres (1,779,730 ha), more than 4% of the state's roughly 100 million acres of land, making 2020 the largest wildfire season recorded in California's modern history, though roughly equivalent to the pre-1800 levels which averaged around 4.4 million acres yearly and up to 12 million in peak years. California's August Complex fire has been described as the first "gigafire", burning over 1 million acres across seven counties, an area larger than the state of Rhode Island. The fires destroyed over 10,000 structures and cost over $12.079 billion in damages, including over $10 billion in property damage and $2.079 billion in fire suppression costs. The intensity of the fire season has been attributed to a combination of more than a century of poor forest management and higher temperatures resulting from climate change.
The 2020 Arizona wildfire season was a series of wildfires that burned across the state of Arizona. The season is a part of the 2020 Western United States wildfire season. With 2,520 fires burning 978,519 acres (395,993 ha) of land, it was the largest wildfire season in Arizona since 2011. Wildfires occur year-round in the state but are most numerous and typically burn the largest swaths of land during spring and summer. Peak fire season in the Southwest typically runs from May, when conditions are windy, hot, and dry, through mid-July, when the North American Monsoon provides the region with precipitation to slow fire activity.
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. The complex originated as 38 separate fires started by lightning strikes on August 16–17, 2020. Four of the largest fires, the Doe, Tatham, Glade, and Hull fires, had burned together by August 30. 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 Santiam Fire was a very large wildfire that burned in Marion, Jefferson, Linn, and Clackamas Counties, in northwest Oregon, United States. Having ignited in August of 2020, the 402,274-acre (162,795 ha) fire ravaged multiple communities in northwestern Oregon, before it was fully contained on December 10, 2020. The fire started as three separate fires. The Beachie Creek, Lionshead, and P-515 fires were ignited by lightning on August 16, 2020. The first three fires gradually grew in size, before explosively spreading in early September during a heatwave, fanned by powerful east winds. Early on September 8, the Beachie Creek and Lionshead Fires merged, and the combined fire was labeled the Santiam Fire, before being returned to their original names a couple of days later. The P-515 Fire merged into the Lionshead Fire a few days later. The Santiam Fire destroyed over 1,500 structures, including the cities of Detroit and Gates, with Idanha, Mill City, and Lyons suffering varying amounts of damage, becoming one of the most destructive wildfires in the recorded history of Oregon. The fire killed five people. On September 10–12, 2020, there were fears that the Santiam Fire would merge with the Riverside Fire to the north.
The Western United States experienced a series of major wildfires in 2020. Severe August thunderstorms ignited numerous wildfires across California, Oregon, and Washington, followed in early September by additional ignitions across the West Coast. Fanned by strong, gusty winds and fueled by hot, dry terrains, many of the fires exploded and coalesced into record-breaking megafires, burning more than 10.2 million acres of land, mobilizing tens of thousands of firefighters, razing over ten thousand buildings, and killing at least 37 people. The fires caused over $19.884 billion in damages, including $16.5 billion in property damage and $3.384 billion in fire suppression costs. Climate change and poor forest management practices contributed to the severity of the wildfires.
