Diana Santos is a Mexican voice actress and dubbing director, recognized as one of the most prolific and enduring talents in the Latin American dubbing industry. Born Alicia Diana Santos Colmenero on June 9, 1950, in Mexico City, she comes from a family with a rich legacy in dubbing, being the daughter of the renowned actor and director Edmundo Santos, the niece of Francisco Colmenero, and cousin of Cristina Camargo. She began her career at the age of six in 1956 and has remained active for over six decades.

Santos is perhaps best known as the official Spanish voice of Minnie Mouse for Disney, a role she has performed from the 1960s to the present day. However, her portfolio is extensive and includes voicing protagonists in numerous classic anime series and films for the Mexican market. She provided the voice for the title character, Hols, in the 1968 film Horus: Prince of the Sun, and for Jack in Jack and the Witch. She also voiced the lead role in The Adventures of Hutch the Honeybee, Demetán in The Brave Frog, Pedro in Puss 'n Boots, and Fritz in Hans Christian Andersen's The Little Mermaid. In the series Heidi, Girl of the Alps, she voiced both Peter and Klara Sessemann, and she was the voice of Yam Yam in the first Mexican dub of Hakushon Daimaō. Her work also includes voicing Smurfette in The Smurfs, Sunni Gummi in Adventures of the Gummi Bears, and later in her career, roles such as Mrs. Kageyama in Mob Psycho 100.

In addition to her acting work, Santos has also worked as a dubbing director, a role she was encouraged to take on by her uncle, Francisco Colmenero. Her contributions to the industry were honored in November 2020 when she received a lifetime achievement award at the second Premios Lavat ceremony in Mexico City, recognizing her 64-year career.
