Megadeth is an American heavy metal band from Los Angeles, California. Guitarist Dave Mustaine and bassist David Ellefson formed the band in 1983 shortly after Mustaine's dismissal from Metallica. Along with Metallica and Slayer, Megadeth is one of the "big four" of American thrash metal, responsible for its development and popularization, their music features complex arrangements and fast rhythm sections, lyrical themes of death, politics, personal relationships and religion. In 1985, Megadeth released its debut album, Killing Is My Business... and Business Is Good!, on the independent record label Combat Records, to moderate success. It caught the attention of bigger labels, their first major-label album, Peace Sells... but Who's Buying?, was released in 1986 and was a major hit with the underground metal scene. Substance abuse and personal disputes brought Megadeth negative publicity during this period. After the lineup stabilized, Megadeth released a number of platinum-selling albums, including Rust in Peace and Countdown to Extinction.

These albums, along with worldwide tours, brought them public recognition. The band temporarily disbanded in 2002 when Mustaine suffered an arm injury and re-established in 2004 without bassist Ellefson, who had taken legal action against Mustaine. Ellefson settled out of court and rejoined in 2010. Megadeth has hosted its own music festival, several times since July 2005. Megadeth has sold 38 million records worldwide, earned platinum certification in the United States for six of its fifteen studio albums, received twelve Grammy nominations. Megadeth won its first Grammy Award in 2017 for the song "Dystopia" in the Best Metal Performance category; the band's mascot, Vic Rattlehead appears on album artwork and live shows. The group has drawn controversy for its music and lyrics, including album bans and canceled concerts. On April 11, 1983, Dave Mustaine was fired from Metallica just prior to the band recording their debut album Kill'Em All due to substance abuse and personal conflicts with James Hetfield and Lars Ulrich.

As Metallica's lead guitarist since 1981, Mustaine had composed some of the group's early songs and helped hone the band into a tight live unit. Afterward, Mustaine vowed revenge by forming a band, faster and heavier than Metallica. On the bus trip back to Los Angeles, Mustaine found a pamphlet by California senator Alan Cranston that read: "The arsenal of megadeath can't be rid no matter what the peace treaties come to." The term "Megadeath" stuck with Mustaine and he wrote a song with the spelling changed to Megadeth, according to Mustaine, represented the annihilation of power. After arriving back in Los Angeles, Mustaine began the search for new bandmates, he formed a band with his new neighbors David Ellefson and Greg Handevidt, who had moved from Minnesota and played bass and guitar. While Handevidt would only last a few months and Ellefson formed a tight musical bond. Despite his enthusiasm, Mustaine had trouble finding other members to fill out the lineup, he and Ellefson auditioned about fifteen drummers, hoping to find one who understood metre changes in music.

After playing with Dijon Carruthers, they selected Lee Rausch. Following six months of trying to find a lead singer, Mustaine decided to fill the role himself. In 1984, Megadeth recorded a three-song demo tape featuring Mustaine and Rausch; the demo tape, Last Rites, was released on March 9, 1984. The demo featured early versions of "Last Rites/Loved to Death", "The Skull Beneath the Skin", "Mechanix", all of which appeared on the band's debut album; the band were unable to find a compatible second guitarist. Kerry King of Slayer filled in on rhythm guitar for several shows in the San Francisco area in the spring of 1984. Afterwards, King went back to Slayer and Megadeth replaced Rausch with jazz fusion drummer Gar Samuelson. Samuelson had been in the jazz band the New Yorkers with guitarist Chris Poland. After seeing Samuelson perform with Megadeth as a trio, Poland went backstage and suggested an impromptu audition as lead guitarist for the band. After considering several labels, Mustaine signed the band to Combat Records, a New York-based Independent record label that offered Megadeth the highest budget to record and tour.

In 1985, Combat Records gave the band $8,000 to produce its debut album. After spending $4,000 of the budget on drugs and food, the band fired the original producer and finished the recording themselves. Despite its low fidelity sound, Killing Is My Business... and Business Is Good! was successful in underground metal circles and attracted major-label interest. Music writer Joel McIver praised its "blistering technicality" and stated that the album "raised the bar for the whole thrash metal scene, with guitarists forced to perform more and powerfully"; the front cover marked the debut of band mascot Vic Rattlehead, who appeared on subsequent album artwork. Killing Is My Business... and Business Is Good! Features "Mechanix", a song Mustaine wrote during his time with Metallica. Though Mustaine told the band after his dismissal not to use the music he had written, Metallica recorded a different version of the song, "The Four Horsemen", with a slower tempo and a melodic middle section; the album included a cover of Nancy Sinatra's "These Boots Are Made for Walkin'," at a faster tempo and with altered lyrics.

Megadeth's version generated controversy during the 1990s, when its writer, Lee Hazlewood, called Mustaine's changes "vile and offensive". Under threat of legal action, the so
