Miles Luna is a Mexican-American writer, director, and voice actor, widely recognized for his extensive work with the production company Rooster Teeth. He began his career at the company assisting with the machinima series Red vs. Blue, and over time, he took on significant writing and directing roles for the series, most notably as the showrunner for its Chorus Trilogy story arc. Luna also co-created and voiced the character David in the Rooster Teeth animated series Camp Camp.

His most prominent voice role is Jaune Arc in the long-running animated series RWBY, a character he has voiced since the show's inception in 2013. He reprised this role for the Japanese anime adaptation, RWBY: Ice Queendom, providing the English voice for Jaune Arc in the series' English dub. This adaptation saw the original English voice cast, including Luna, return to their roles. In addition to Jaune Arc, his other notable voice work within the Rooster Teeth library includes voicing the antagonist Felix in Red vs. Blue.

Throughout his career, Luna has been part of recurring collaborations with fellow Rooster Teeth creators and voice actors, such as Kerry Shawcross, with whom he frequently worked on writing and directing projects, and Lindsay Jones, Kara Eberle, Arryn Zech, and Barbara Dunkelman, who form the core cast of RWBY alongside him. His contributions to animation have been recognized with two International Academy of Web Television Awards for Best Animated Series for his work on Red vs. Blue Season 10 and RWBY Volume 1. In 2020, Luna departed from his full-time position as Head Writer of Animation at Rooster Teeth to pursue freelance opportunities, though he continues to work as a voice actor.
