Regina Beckhaus is a German-American voice actor and actress known for her work in dubbing foreign-language films and series for the German market. Born on December 31, 1992, in Würzburg, Germany, she grew up bilingual, speaking both German and English, a skill that has become a cornerstone of her professional career.

Her path to voice acting was built on a foundation in the performing arts. From a young age, Beckhaus was involved in dance, training professionally until the age of sixteen, and began taking professional singing lessons when she was twelve. She later pursued formal training in acting at a school in Munich, graduating as a state-recognized actress. While working as a speaker for corporate videos during her acting studies, her talent was recognized by a dubbing director in early 2014, which led her to focus on a career in voice acting.

In the realm of anime, Beckhaus is prominently known for voicing the Natural Killer Cell in the German dubs of the popular series Cells at Work! and Cells at Work!! The dubs for these series were produced by the Tonwerk studio in Munich. Her role as a key immune cell in this educational and entertaining series is a notable credit in her filmography.

Beyond Cells at Work!, Beckhaus's voice work in anime includes a variety of other roles. She is credited with voicing Toole in Fate/Apocrypha, Rani VIII in Fate/Extra, and Hrist in Record of Ragnarok. She has also lent her voice to characters in series such as Forest of Piano, Super HxEros, and the Pokémon Sun & Moon anime. While her anime roles are diverse, the majority of her extensive dubbing work is for live-action productions.

Her broader career as a German voice actor is marked by a high volume of work in international film and television. She is the regular German voice for actresses such as Brenna D'Amico (in the Descendants film series) and Tawny Newsome. Other prominent dubbing credits include voicing Marta Cabrera for Ana de Armas in Knives Out, Echo for Tasya Teles in the series The 100, and Mysaria in House of the Dragon. Her filmography also includes voice work in major video games and trailers.
