Uki Satake is a Japanese voice actor, singer, and actress born on March 8, 1992, in Tokyo, Japan. She began her entertainment career after being scouted in the Shibuya district in 2005. Her career is multifaceted, as she is also a member of the Japanese girl group 9nine and has worked as a model and television actress. She has hosted her own radio program, Satake Uki no Uchū wo Kirei ni Suru Radio, since 2012.

Satake's career in voice acting began around 2010. One of her most prominent and long-running roles is Tsubomi in the anime adaptation of Mob Psycho 100, a part she has played since the first season in 2016 through to the third season. She was cast as the protagonist Kirie Goshima in the highly anticipated anime adaptation of Junji Ito's horror manga Uzumaki, a role she described as particularly challenging due to the nature of performing fear and terror for the anime. In an interview, she noted that horror roles are difficult because they require constant screaming and conveying the experience of being frightened.

Other noted voice roles include QT in Space Dandy, Lisa in the short form anime series Lazarus, and the sarcastic AI rabbit Aladdin in Carole & Tuesday. Her work demonstrates a versatility that ranges from quiet, normal characters like Tsubomi to the intense emotional demands of a horror protagonist and the dual nature of a cute but ill-tempered animated toy.
