Andrea Kathrin Loewig is a German actress and voice actor, born on September 22, 1966, in Merseburg. She trained at the Ernst Busch Academy of Dramatic Arts and the State Ballet School in Berlin, later supplementing her education with a Hollywood Acting Workshop in Los Angeles in 1998. While she is widely recognized by German television audiences for her long-standing role as Dr. Kathrin Globisch in the ARD hospital series In aller Freundschaft since 1999, her voice is also familiar from a vast body of synchronization work.

In the realm of anime and animation dubbing, Loewig is best known as the German voice of the character Ai Haibara. She has voiced this role consistently across the long-running anime series Detective Conan, its associated films from the third to the fifteenth, and in crossover productions such as Lupin III vs. Detective Conan: The Movie. This role connects her to the original Japanese voice actor Megumi Hayashibara, whom she dubs for this character. Her other animation voice work includes the role of a mother penguin in the German version of the documentary film March of the Penguins.

Beyond anime, Loewig's voice acting career is extensive, primarily focused on dubbing live-action film and television. A notable recurring collaboration is with actress Charlize Theron; her German voice for Theron's performance in the film Monster earned her the Deutscher Synchronpreis (German Synchron Award) for Outstanding Female Dubbing Work in 2004. She is also the German narrative voice for the series Desperate Housewives and has dubbed numerous other prominent actresses in series such as Scrubs, Buffy the Vampire Slayer, The O.C., and Cold Case. Her professional profile lists a vast number of credited synchronization roles for a wide array of actresses, demonstrating her versatility and extensive activity in the field.
