Lisa Nicole Lopes (May 27, 1971 – April 25, 2002), better known by her stage name Left Eye, was an American hip hop singer, rapper, actress, songwriter and producer. She rose to fame in the early 1990s as one-third of the girl group TLC, alongside Tionne "T-Boz" Watkins and Rozonda "Chilli" Thomas. Besides rapping and singing background vocals on TLC recordings, Lopes was one of the creative forces behind the group. She received more cowriting credits than the other members. She also designed the outfits and stage for the group and brought concepts to the group image, album titles, artworks and music videos. Through her work with TLC, Lopes won four Grammy Awards.

During her short solo career, Lopes scored two US top-ten singles with "Not Tonight" and "U Know What's Up", as well as one UK number-one single with "Never Be the Same Again". She also produced the girl group Blaque, who scored a platinum album and two US top-ten hits. Lopes remains the only member of TLC to have released a solo album.

On April 25, 2002, Lopes was killed in a car accident while on a retreat with her sister and others. She swerved off the road to avoid hitting another vehicle and was thrown from her vehicle and died instantly. The last days of her life were made into a documentary called The Last Days of Left Eye, which aired on VH1 in May 2007.
