Claire Elise Boucher (born March 17, 1988), better known by the stage name Grimes, is a Canadian singer, songwriter, music video director, and record producer. Born and raised in Vancouver, she first became involved with the underground music scene and began recording her own experimental music while attending McGill University in Montreal.

Boucher released the studio albums Geidi Primes and Halfaxa through Arbutus Records in 2010, and signed a secondary recording contract with 4AD in 2011. Her third studio album Visions (2012) and its singles "Genesis" and "Oblivion" received widespread critical acclaim; it was hailed as "one of the most impressive albums of the year so far" by The New York Times, was nominated for the Polaris Prize, and received the Juno Award for Electronic Album of the Year. Her fourth studio album Art Angels was released in 2015 and has since become her highest-charting project in the United States peaking at number 36.

Grimes' music has been noted by critics and journalists for its atypical combination of vocal elements, as well as a wide array of influences across electronica and pop, hip hop and R&B, experimental and medieval music. In 2013, Grimes was awarded the Webby Award for Artist of the Year.
