Macy Anne Johnson is an American voice actor known for her work in the English dubs of anime series and films. She is based in Texas and frequently provides voices for productions by Funimation and Crunchyroll. Johnson confirmed in a 2019 interview that she was attending university as a theater arts major, balancing her education with her growing career in voice acting. Her professional journey began in high school when she landed her first job voicing the character Dreadful Doll Izanami in the video game Smite. She credits her background in theater performance, from which she graduated in 2022, as a significant influence on her approach to voice acting, noting that she often uses physical movement in the recording booth to inform her vocal performance.

Johnson has accumulated a wide range of notable roles across various anime series. She voices the title character Shikimori in Shikimori's Not Just a Cutie and Swindler in Akudama Drive. In longer-running series, she has taken on roles such as a younger version of the character Big Mom in One Piece and Emile in Spy X Family. Other prominent credits include Howan in Show By Rock!! Mashumairesh!!, Shouta in Miss Kobayashi's Dragon Maid S, Mei in Hell's Paradise, Chiyuki Fujito in Smile Down the Runway, and Kaede in Gal and Dino.

She is also part of the voice cast for One Piece Film: Red.

Johnson is not only an actor but also contributes to anime production as an ADR scriptwriter. She has written English dub scripts for several series, including Trigun Stampede, The Devil is a Part-Timer Season 2, More than a Married Couple, but Not Lovers, Why Raeliana Ended up at the Duke's Mansion, and My Clueless First Friend. This dual role as both performer and writer reflects a deep engagement with the localization process.

Johnson's career is marked by frequent collaborations with other voice actors and directors within the industry. For the English dub of Magical Girl Raising Project, she was cast as Hardgore Alice, working under the direction of Jad Saxton and with a script by Kristen McGuire.
