Haulston Mann is an American voice actor known for his work in English dubs of anime series. He grew up in northeastern Arkansas, where he first became interested in acting as a child, performing in a local community theatre production of High School Musical when he was around sixteen or seventeen years old. His background also includes songwriting and playing small gigs with his brother.

Mann is perhaps best known for his role as Hans Obermayer (also spelled Hans Obermeyer) in the anime series Izetta: The Last Witch (2016). Set in an alternate version of twentieth-century Europe, the fantasy war series tells the story of a young witch who protects a small country from invading forces. Mann voiced Hans Obermayer, a secondary character who appears in five episodes of the series. The English voice cast for Izetta: The Last Witch also included Mallorie Rodak as Finé, Skyler McIntosh as Izetta, John Burgmeier, Christopher Wehkamp, and others.

Also in 2016, Mann provided English voice work for two characters in the crime anime series 91 Days. He voiced Tigre in the episode Slipping Through the Dirty Sky and Ganzo in the episode All for Nothing. His anime voice acting credits show him working alongside several Funimation-based voice actors such as John Burgmeier and Christopher Wehkamp.

Beyond anime, Mann has appeared in several live-action independent films. His film credits include The Crossroads of Hunter Wilde (2019), One for the Road (2023), Group (2023), Guys at Parties Like It (2024), Killington (2024), Halmoni's Pot (Grandma's Pot) (2024), How to Start a Cult in 5-Easy Steps (2025), and A Home for Christmas (2025).
