Third Album is the third studio album released by The Jackson 5 on Motown Records, and the group's second LP released in 1970. Third Album featured the group's fourth consecutive number-one single on the US pop charts, "I'll Be There", the Top 5 single, "Mama's Pearl", and album tracks such as the semi-autobiographical "Goin' Back to Indiana", and "Darling Dear". The album peaked at #4 on the Billboard album charts and #1 on the R&B album charts and also #1 on Cashbox. This is considered one of their best efforts and is their most successful album to date. It sold over 6 million copies worldwide. The album is known in some countries as I'll Be There(アイル・ビー・ゼア?).
Allmusic's Lindsay Planer rated Third Album four out of five stars. She stated that the album contains "the unmistakable Motown sound, expanding just enough to incorporate other significant influences as well." She also stated that a few of the tracks "are [...] worthwhile spins."
In 2001, Motown Records remastered all J5 albums in a "Two Classic Albums/One CD" series (much like they did in the late 1980s). This album was paired up with Maybe Tomorrow. The bonus tracks were "Sugar Daddy", the only new track on their 1971 greatest hits set, and "I'm So Happy", the B-side of that single.
