The Jackson 5, or Jackson Five, currently known as the Jacksons, are an American family music group. Formed around 1964, the founding members were elder brothers Jackie, Tito and Jermaine. Younger brothers Marlon and Michael would join soon after. They participated in talent shows and performed in clubs on the Chitlin' Circuit. They entered the professional music scene in 1967, signing with Steeltown Records and releasing two singles with the Steeltown label. In 1969, the group left Steeltown Records and signed with Motown.

The Jackson 5 were the first group to debut with four consecutive number one hits on the Hot 100 with the songs "I Want You Back", "ABC", "The Love You Save", and "I'll Be There".

Inducted to the Rock and Roll Hall of Fame in 1997 and the Vocal Group Hall of Fame in 1999, the Jacksons reunited in 2001 on Michael's 30th anniversary television special. Following the death of Michael Jackson in 2009, the four eldest of the brothers embarked on their Unity Tour in 2012.
