Willow Johnson is a Canadian voice actress known for her extensive work in English language dubs of anime series, primarily recorded in Vancouver. Born on April 3, 1977, she has been active in the voice acting industry since 1988, with her first role in animation being on the Canadian show Camp Candy at the age of twelve. She is closely associated with Ocean Productions, a major Vancouver-based voice acting company.

Johnson is perhaps best known to fans of the manga artist Rumiko Takahashi for her roles in two of Takahashi's most famous series. She provided the voice for Kasumi Tendo, the eldest of the Tendo sisters, in various adaptations of Ranma ½, including the main television series and films such as Team Ranma vs. The Legendary Phoenix. Her most prominent and recurring role is that of Kikyo in the InuYasha franchise. She voiced the character throughout the original InuYasha series, its four movies including The Tragic Love Song of Destiny, and the concluding series Inuyasha: The Final Act. She later reprised a version of this role in the sequel series Yashahime: Princess Half-Demon and its second act, where she voiced the Spirit of the Tree of Ages, a character that takes on Kikyo's form.

Beyond these signature roles, her anime filmography includes a wide range of characters from the 1980s through the 2020s. Notable credits include Lalah Sune in various Mobile Suit Gundam productions, Yukari Uchida in The Vision of Escaflowne, Ruby Moon in Cardcaptors, Android 18 in the later episodes of Dragon Ball Z, and Tomihime in Ayakashi: Samurai Horror Tales. She also voiced the role of Yukie in the anime adaptation of Mermaid's Scar. Her work has also extended into animated series and video games, lending her voice to characters in projects like My Little Pony Tales, Barbie and the Three Musketeers, and various games based on the Inuyasha and Gundam franchises.

Throughout her career, Johnson has frequently collaborated with a consistent group of voice actors based in the Vancouver talent pool. She has worked alongside actors such as Kelly Sheridan, Kirby Morrow, and Cathy Weseluck on numerous projects, contributing to the distinct sound of many anime dubs produced in the city during the 1990s and 2000s. Her long-standing association with the works of Rumiko Takahashi, particularly the characters of Kasumi Tendo and Kikyo, stands as a significant achievement in her career, marking her as a recognizable voice for fans of English-dubbed anime from that era.
