Christina Victoria Grimmie (March 12, 1994 – June 10, 2016) was an American singer-songwriter, actress and YouTuber. In 2009, she began posting covers of popular songs onto YouTube. After releasing her debut EP, Find Me (2011), her YouTube channel reached one million subscribers. After she reached two million subscribers, she released her debut studio album, With Love (2013).

Grimmie then became a contestant on season six of The Voice, finishing in third place. Adam Levine, her coach on the show, announced in the finale that, regardless of the results, he would sign her to his label 222 Records. Lil Wayne also offered to sign her to his label, Young Money Entertainment. She was signed with Island Records for a short time before being dropped. Grimmie released her second EP, Side A, in 2016. That same year, she took on an acting role, making her only motion-picture appearance in The Matchbreaker.

On June 10, 2016, Grimmie was shot dead while signing autographs following a concert performance at The Plaza Live in Orlando, Florida. Side B, a follow-up to Side A, was made available on Spotify and iTunes in 2017, and in June 2017, Grimmie's second and final album, All Is Vanity, was released posthumously. In 2019, her YouTube channel reached four million subscribers, although it dropped below four million in 2020, settling at 3.88 million as of October 2024.
