Charlie Green V (born May 10, 1999), better known online as CG5, is an American YouTuber, musician, singer, songwriter, and music producer from Phoenix, Arizona. He creates original songs, remixes, and covers based upon video games, viral memes, television shows, and original concepts. CG5 is also known for his collaborations with other music artists and producers, such as Caleb Hyles, DHeusta, and RichaadEB.

CG5’s most notable songs are based on well-known gaming topics, like the Dream SMP (a roleplay Minecraft server), and popular games such as Five Nights at Freddy’s (FNaF), Cuphead, and Among Us. Influences on his music include ‘70s and '80s pop and groups like Hall & Oates and The Doobie Brothers.

Although Charlie launched his main channel on YouTube in 2014, it began to grow in 2017 due to the success of his FNaF tracks, “Can I Get An Amen,” “I Got No Time,” and “Labyrinth.” These songs cemented him as a pioneer of the FNaF community to the point where he cites the fandom as one of his biggest influences on his childhood.

In the same year, Charlie gained a different type of popularity among TikTok users with his single, “Absolutely Anything.” The song trended on the platform and was picked up by Spinnin' Records/Warner for re-distribution. It is Charlie’s first commercial label release. He has continued to make nerdcore songs since then, such as “I See A Dreamer,” “Lyin 2 Me,” and “SUPERSTAR,” the latter being his first FNaF-themed song since months.
