The Ariel Award for Best Actress is an award presented by the Academia Mexicana de Artes y Ciencias Cinematográficas (AMACC) in Mexico. It is given in honor of an actress who has delivered an outstanding performance in a leading role while working within the Mexican film industry. In 1947, the 1st and 2nd Ariel Awards were held, with Dolores del Río and María Félix winning for the films Las Abandonadas and Enamorada, respectively. With the exception of the years 1959 to 1971, when the Ariel Awards were suspended, the award has been given annually. Nominees and winners are determined by a committee formed every year consisting of academy members, previous winners and individuals with at least two Ariel nominations; the committee members submit their votes through the official AMACC website.

María de los Ángeles Félix Güereña was a Mexican actress and singer. Along with Pedro Armendáriz and Dolores del Río, she was one of the most successful figures of Latin American cinema in the 1940s and 1950s. Considered one of the most beautiful actresses of the Golden Age of Mexican cinema, her strong personality and taste for finesse garnered her the title of diva early in her career. She was known as La Doña, a name derived from her character in Doña Bárbara (1943), and María Bonita, thanks to the anthem composed exclusively for her as a wedding gift by Félix's second husband, Agustín Lara. Her acting career consists of 47 films made in Mexico, Spain, France, Italy and Argentina.
