Christopher Llewyn Ramirez is an American voice actor known for his work in English dubs of anime series, primarily for productions by companies like Funimation and Crunchyroll. His career encompasses a range of supporting and lead roles across various genres, from sports dramas to supernatural adventures.

Ramirez's voice acting credits include several prominent anime series. He voiced the character Eisaku Ohtomo in the sports anime Aoashi, providing the English voice for the first half of the series before being succeeded by another actor. In the romantic comedy Horimiya, he took on the role of Koichi Shindo, a friend of the main characters, and later reprised this role for the 2023 sequel series Horimiya: The Missing Pieces. He also voiced the character Seth, the energetic protagonist of the fantasy adventure series Radiant. His other notable roles include the cheerful swimmer Asahi Shiina in Free! -Dive to the Future-, Shinobu Sengoku in the idol franchise Ensemble Stars!, and Ryuji Yoshioka in After School Dice Club.

One notable aspect of his career was his temporary departure from the series Aoashi after episode 13 to perform in a production with the Dallas Theatre Center, at which point his role was taken over by another voice actor. This highlights a recurring theme in his filmography, which often includes collaborations with a consistent group of voice actors common to the Texas-based dubbing industry, such as Marisa Duran, Jordan Dash Cruz, and Mark Allen Jr., among others. His return to voice Koichi Shindo in the later Horimiya sequel also demonstrates his continued association with certain franchises and characters over time.
