Maribel Altés is a Spanish actress with a career spanning theater, television, and dubbing, born in the Sarrià district of Barcelona in February 1943. Her interest in performance began early; she started studying dance at the Institut del Teatre at the age of twelve and made her first forays into acting, both in television and amateur theater, at fifteen. Her professional stage debut was at the Teatro Español in Madrid under the direction of Adolfo Marsillach, and her artistic career later became centered in Barcelona.

In addition to her on-screen and stage work, Altés developed a significant career in dubbing, lending her voice to numerous characters for Spanish-language versions of films and television series. A database of dubbing professionals credits her with a substantial body of voice work from the 1980s through at least 2007, primarily for productions dubbed in Spain. These credits include a wide range of secondary characters and voice roles in international productions such as providing a voice for the film Aliens, dubbing an actress in the television series Murder, She Wrote on multiple occasions, and contributing to the Spanish dubbing of films like Quills.

Regarding voice work in anime, Altés is recognized for her role in the film version of the classic series Queen Millennia. In this feature film, she provided the Spanish voice for the character Larela. While her dubbing credits are extensive, this particular role is one of the few directly associated with the anime genre. The available information on her career points to a prolific and long-standing profession in dubbing for a variety of media, with her contribution to anime being a specific, but not singularly defining, part of her broader portfolio as a voice actress.
