Olga Jankowski is an anime voice actor known for her work in the English-language dub of the popular franchise Girls und Panzer. Her most prominent role is providing the voice for the character Klara in the 2015 film Girls und Panzer der Film. Klara is a foreign exchange student from Russia who attends Pravda Girls High School and is a skilled tank commander and gunner. This casting was part of the English dub produced by Sentai Filmworks, which featured a large ensemble cast and was released in North American theaters in November 2016.

Jankowski's involvement with the Girls und Panzer series continued in later installments. For the subsequent six-part theatrical series Girls und Panzer das Finale, the voice cast saw several changes. In this series, Jankowski took on the role of the character Nonna, who is also a key member of the Pravda team, while the role of Klara was voiced by a different actor. This casting shift demonstrates her recurring collaboration with the franchise and its English dubbing production team. Beyond her work as Klara and Nonna in the Girls und Panzer films, no other widely documented anime voice acting roles for Olga Jankowski are readily identifiable in standard industry resources.
