Jacks may refer to:
Jacks were a 1960s Japanese psychedelic rock group who released their best known studio album Vacant World in 1968.
The Jacks, originally known as "Nightingale", began their career in 1966 as a folk trio. After jazz drummer Takasuke Kida joined the group they headed into a new musical direction. Vacant World, released in 1968 as Karappo No Sekai [Vacant World] or Jacks no Sekai [Jacks' World] in Japanese, is widely seen as one of the most important Japanese albums. The song "Vacant World" (or "Karappo no Sekai" in Japanese) was famously banned from Japanese airwaves due to lyrical content. The Jacks' musical legacy has carried on in Japan despite the fact that their career was quite short, disbanding shortly before the release of their second studio album Super Session (Jacks No Kiseki in Japanese).
After the breakup of Jacks, singer Yoshio Hayakawa released one acclaimed solo album before retiring from music, only to reemerge again as a solo artist during the 1990s. Drummer Takasuke Kida died in a car accident in 1980.
