Ble (Greek: Μπλε, romanized: Mple , literally Blue) is a Greek pop rock band, formed in 1996 by George Papapostolou (guitar, sax, vocals, music) and George Parodis (lyrics). Theodosia Tsatsou (lead vocals) and Natasa Alexiou (backing vocals, violin) completed the current lineup of the band in 1996. The name Ble (Μπλε in Greek) means blue. Their music is characterised by their dark and introspective album, Enohes.

In 1997, Theodosia Tsatsou left the band and Ble continued successfully with a new singer, Georgia Kefala, who still remains the lead singer of the band.

The group has released six studio albums: Enohes (1996), Ble (1998), Ela Na Deis (2000), Sta Mavra Eho Ntithei (2002), Etsi Thelo Ego Na Zo (2004) and Oneira Sou Tragoudao (2006). In 2009 they released Ble 1996–2009 compilation (Best Of). The band had success with "Niotho Enohes" from their first single and "Fovame" from the album Enohes, which became a hit single in 1996. Ble's second album, Ble, featured a harder and heavier sound. Their third album, Ela Na Deis, was released in 2000. Since then, they released three more albums with success in the Greek charts.
