Rachael Leigh Cook is an American actress and voice artist whose work in anime and video game dubbing is most defined by her long-running portrayal of Tifa Lockhart from the Final Fantasy VII series.

Cook began her voice work in animation with a role in the DC animated universe, providing the voice for Chelsea Cunningham on the series Batman Beyond and reprising the character for the animated film Batman Beyond: Return of the Joker. She also became a frequent contributor to the stop-motion comedy series Robot Chicken, voicing various characters across multiple episodes. Her other recurring animated voice role was as Lieutenant Jodi Yanarelli on the sci-fi comedy series Titan Maximum.

Her most significant and enduring contribution to anime voice acting came in 2005 with the English dub of the CGI film Final Fantasy VII: Advent Children, in which she voiced Tifa Lockhart. Cook's portrayal of Tifa, described by the actress as a character who is both very strong and very sensitive, became the established English voice for the character in subsequent projects. Following Advent Children, she reprised the role of Tifa in numerous video games, including Kingdom Hearts II, Dirge of Cerberus: Final Fantasy VII, Dissidia 012 Final Fantasy, World of Final Fantasy, and Dissidia Final Fantasy NT. Her tenure as the English voice of Tifa Lockhart spanned from 2005 to 2019. Beyond Final Fantasy, her other notable video game voice roles include Reina in Yakuza and Jaesa Willsaam in the massively multiplayer online game Star Wars: The Old Republic.
