Yuki Horinaka is a Japanese female voice actress from Tokyo, born on August 18. Her blood type is AB. She made her debut in 2009 and became a freelancer in the spring of 2017 after being affiliated with several agencies.

Horinaka's career began after she passed a voice actor audition in the autumn of 2008. She joined the agency Production Ace in 2009. Her debut and most prominent role came in 2009 when she was cast as Mafuyu Shiina in the anime adaptation of the light novel series Student Council's Discretion. She left Production Ace at the end of October 2010. In September 2011, she joined Ken Productions, but departed from that agency on March 31, 2017, after which she began working as a freelancer.

One of the most notable events in her career was being replaced in the role of Mafuyu Shiina for the second season of Student Council's Discretion, which aired in 2012. Voice actress Iori Nomizu took over the part. While her debut role was well-received, her subsequent prominent anime appearances were limited.

Despite this, Horinaka built a significant body of work in video games. Her most recurring role is as the character Elize Lutus, which she originated in the 2011 role-playing game Tales of Xillia. She reprised this role in its sequel, Tales of Xillia 2, and in several other games in the series, including Tales of Asteria, Tales of the Rays, and the mobile title Granblue Fantasy. Another notable game role is Genny in Fire Emblem Echoes: Shadows of Valentia and Fire Emblem Heroes. Her other anime and game credits include roles in Jewelpet Happiness, where she played Dorothy and Angel, Kuroko's Basketball, and Moero Chronicle.
