Kelsey Cruz, also known by her maiden name Kelsey Maher, is an American voice actor based in Texas who works extensively in English-language anime dubbing. Originally from Seattle, Washington, she developed an interest in acting from a young age and initially pursued a different path, studying at a leadership college with the goal of becoming a children's pastor. Her involvement in skits during that time reaffirmed her passion for performance, leading her to audition for and enroll in the Bachelor of Fine Arts program in acting for the stage and screen at Azusa Pacific University in 2014, from which she graduated in 2017.

After graduating, Cruz remained in Los Angeles seeking work in film before transitioning into voice acting. Her entry into the field began with recording audiobooks, which she found to be a valuable learning experience. She further honed her skills by taking classes at voice-over studios, including Real Voice LA and a Bang Zoom! workshop led by Tony Oliver. A significant step in her career came during the COVID-19 pandemic when she was encouraged by fellow voice actor Jordan Dash Cruz, whom she later married, to audition for Crunchyroll, the Dallas-based company specializing in English dubs. Since then, she has provided voices for a wide array of characters in over one hundred anime series, working with Crunchyroll as well as a freelance actor at other studios.

Cruz has voiced numerous roles across various genres. Her credits include Vania in I've Been Killing Slimes for 300 Years and Maxed Out My Level, Kris Argent in Let This Grieving Soul Retire, Yaeko Kirihara in Dekin no Mogura: The Earthbound Mole, Lulu in Scooped Up by an S-Rank Adventurer, Reina Aharen in Aharen-san wa Hakarenai, Asahi Shonan in Medaka Kuroiwa is Impervious to My Charms, Reyva in Possibly the Greatest Alchemist of All Time, Animalia in Shangri-La Frontier, Yinghua in The Apothecary Diaries, Konoha Satou and Iana Magnolia in The Dark History of the Reincarnated Villainess, and Makina Umezawa in Watari-kun's ****** Is About to Collapse.
