Sharp (stylized as S#arp; Korean: 샵) was a South Korean co-ed pop vocal group that was active from 1998 to 2002.^[1]

The group initially consisted of Lee Ji-hye, Seo Ji-young, Jang Seok-hyun, John Kim and Oh Hee-jong. John and Hee-jong left the group after the release of the group's first album, The S#arp, in 1998. New members Sori and Chris joined the group in 1999 for the second album, The S#arp+2. Sori later left the group, and Sharp went on to release the albums, The Four Letter World Love (2000), 4ever Feel So Good (2001), Flat Album (2001), and Style (2002).^[2] The group disbanded in 2002, reportedly as a result of ongoing conflict between Ji-hye and Ji-young, including verbal and physical assault.^[1][3]

Sharp was one of the few mixed-gender groups active during an era when single-gender groups such as S.E.S., Fin.K.L, Shinhwa and g.o.d were dominating the music scene.^{[citation needed]} The group won #1 on the music programs Inkigayo and Music Bank, tasting their first success in 1999 with "Tell Me Tell Me."^{[citation needed]}
