Original Van Halen frontman David Lee Roth is reuniting with the rock group for a North American tour, according to the band's official website.
David Lee Roth left the band more than 20 years ago
Guitarist Eddie Van Halen said: "I am very excited to get back to the core of what made Van Halen."
Roth last performed live with the band in 1984 before he was replaced a year later by Sammy Hagar.
The rock act, whose biggest hit was Jump, are to be inducted into the US Rock and Roll Hall of Fame next month.
Roth briefly reformed with Van Halen in 1996, resulting in two new songs on a greatest hits compilation, but no concert tour.

The band's original bassist, Michael Anthony, will not be taking part in the reunion tour, expected to visit 40 locations during the summer.
Last year he was replaced in the line-up by Eddie Van Halen's teenage son, Wolfgang.
Van Halen released their self-titled debut album in 1978 and became one of the most influential rock bands of the 1980s, selling an estimated 75 million albums worldwide.
Roth went on to have a solo musical career, and in 2006 became a radio host in the US, temporarily replacing "shock jock" Howard Stern after his move to a satellite-based radio station.
Despite their success in the US, Van Halen failed to score a chart-topping record in the UK, with 2004's Very Best of Van Halen their last chart hit.
Roth and his replacement Hagar embarked on a Heavyweights of Rock and Roll tour together in 2002, but neither of the Van Halen brothers were involved in the project.
