Cate Blanchett is an Australian actress who has provided voice work for animated films, including the English-language adaptation of the Japanese animated feature Ponyo on the Cliff by the Sea. In this 2008 film from Studio Ghibli, directed by Hayao Miyazaki, she voices the role of Granmamare, the goddess of the sea and the mother of the title character, Ponyo. Her performance contributes to a cast that also includes the voices of Liam Neeson, Tina Fey, and Matt Damon for the film's English dub.

While Blanchett is widely recognized for her extensive live-action career, her voice acting work also extends to other animated projects. She voiced the character Valka in the DreamWorks Animation franchise How to Train Your Dragon, first in the 2014 sequel and later in the 2019 film How to Train Your Dragon: The Hidden World. She is also known for voicing characters in English-language animated or hybrid films such as Pinocchio in 2022. Her approach to voice acting involves bringing a character to life using only her voice prior to the animation process, a challenge she has described as interesting. Information regarding recurring collaborations specifically within the anime industry or a broader profile as an anime voice actor remains limited, as her known work in this area is primarily for the English dubbing of Ponyo.
