Kate del Castillo (born October 23, 1972) is a famous Mexican actress. She is the daughter of Eric del Castillo, who is a legend of the Mexican cinema's golden era and a former soap opera actor himself. Some biographers say her actual year of birth was 1974, but 1972 is generally accepted as the year she was born.

A participant in ten telenovelas, del Castillo made her acting debut in 1980 when she participated in a movie named El Ultimo Escape (The Last Escape).

She was catapulted into fame in 1991 when she starred as Leticia in Muchachitas, a soap opera that reached wild popularity all over Latin America. Muchachitas reached the top audience spots in Mexico, Puerto Rico, Venezuela, Peru, and among hispanic audiences in the United States.

Among the other soap operas and movies she made are Ramona, and El Derecho de Nacer (The Right to be Born). In 1996, she married soccer player Luis Garcia, who was very famous in his own right and a member of the Mexican national soccer team. Th marriage did not last too long, however. In 2000, she campaigned for President-to-be Vicente Fox, a fact that did not sit well with Televisa leaders.

In 2002 and 2003, this habitual autograph signer began an international tour alongside Argentinian actor Saul Lisazo, also a superstar in Mexico, with their play Cartas de Amor (Love Letters).
