Van Halen ( van HAY-len) was an American rock band formed in Pasadena, California, in 1973. Credited with restoring hard rock to the forefront of the music scene, Van Halen was known for their energetic live performances and for the virtuosity of its guitarist, Eddie Van Halen. The band was inducted into the Rock and Roll Hall of Fame in 2007.

From 1974 to 1985, Van Halen consisted of Eddie Van Halen, his brother, drummer Alex Van Halen, lead vocalist David Lee Roth, and bassist Michael Anthony. Upon its release in 1978, the band's self-titled debut album reached No. 19 on the Billboard 200 and would sell over 10 million copies in the United States, achieving a Diamond certification by the Recording Industry Association of America (RIAA). By 1982, the band released four more albums: Van Halen II (1979), Women and Children First (1980), Fair Warning (1981), and Diver Down (1982), all of which have since been certified multi-platinum. By the early 1980s, Van Halen was among the most commercially successful rock acts. The album 1984, released in the eponymous year, was a commercial success with U.S. sales of 10 million copies and four successful singles. Its lead single, "Jump", was the band's only number one single on the Billboard Hot 100.

In 1985, Roth left the band to embark on a solo career and was replaced by former Montrose lead vocalist Sammy Hagar. With Hagar, the group released four U.S. number-one, multi-platinum albums over the course of 11 years: 5150 in 1986, OU812 in 1988, For Unlawful Carnal Knowledge in 1991, and Balance in 1995. The group also released a double-platinum live album, Live: Right Here, Right Now, in 1993. Hagar left the band in 1996 shortly before the release of the band's first greatest hits collection, Best Of – Volume I. Former Extreme frontman Gary Cherone replaced Hagar and recorded the commercially unsuccessful album Van Halen III with the band in 1998, before parting ways in 1999. Van Halen then went on hiatus until reuniting with Hagar in 2003 for a worldwide tour in 2004 and the double-disc greatest hits collection, The Best of Both Worlds (2004). Hagar again left Van Halen in 2005. Roth returned in 2006, but Anthony was replaced on bass guitar by Eddie's son, Wolfgang Van Halen. In 2012, the band released their final studio album, A Different Kind of Truth, which was commercially and critically successful. It was also Van Halen's first album with Roth in 28 years and the only one to feature Wolfgang. Eddie was diagnosed with cancer in 2001, and died of the disease on October 6, 2020. A month after his father's death, Wolfgang confirmed that Van Halen had disbanded.

As of March 2019, Van Halen is 20th on the RIAA's list of best-selling artists in the United States; the band has sold 56 million albums in the U.S. and more than 80 million worldwide, making them one of the best-selling groups of all time. As of 2007, Van Halen is one of only five rock bands with two studio albums to sell more than 10 million copies in the United States and is tied for the most multi-platinum albums by an American band. Additionally, Van Halen has charted 13 number-one hits on Billboard's Mainstream Rock chart. VH1 ranked the band seventh on its list of the "100 Greatest Hard Rock Artists".
