Given annually, since 1946, by the Mexican Academy of Cinematographic Arts and Sciences (AMACC), the award recognizes artistical and technical excellence in the Mexican film industry. The purpose of the Ariel recognition is to stimulate and increase the excellence of Mexican cinema, favor the growth of the industry, and promote the meeting and strengthening of the national film community. It is regarded as the most prestigious award in the Mexican film industry and considered Mexico's equivalent to the Oscars of the United States.

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.
