María del Rosario Mendoza (stage name, Rossy Mendoza; June 6, 1950) is a Mexican vedette, actress, dancer and singer. During the 1970s–1980s, she was one of the highest grossing artists in the Mexican sex comedy film genre. Rossy Mendoza was born in Vícam, one of eight Yaqui villages in the south of the Mexican state of Sonora. She began her career in the mid-1960s when she was still a teenager, slowly making a name for herself in the entertainment industry by performing in the main cabarets of Sonora. She also appeared in well known Mexican magazines including Cinelandia, Cine mundial and Siempre. In the late 1960s her physique became athletic and voluptuous, in contrast to the slimness it had in her early years, and she had cosmetic surgery on her nose to improve her facial appearance. In 1964 she made her first appearance at the Teatro Lírico in Mexico City, where other prominent figures such as Tin Tan, El Santo and Sergio Corona performed. In 1968 she joined the cast of the cabaret El Capri, where she worked alongside vedettes such as Yolanda "Tongolele" Montes and the Argentine Zulma Faiad. She appeared in several television programmes such as Sabadito Alegre, with Paco Malgesto, where she remained for several months. In 1970 she worked with the comedian Adalberto Martínez (better known as "Resortes") in El Tenorio Comico at the Blanquita Theater in Mexico City. She appeared there for many seasons, accompanied by an orchestra and a ballet of 18 dancers. Her performances alternated with singers such as Celia Cruz, Enrique Guzmán, Mike Laure, Sonia Lopez and Dámaso Pérez Prado. At the same time she was hired by the Vallejo Family to perform in La Caravan Corona, in which she appeared from 1971 to 1982. This consisted of groups of stars from the show that traveled throughout Mexico and in which she performed with acts such as Los Polivoces (Eduardo Manzano and Enrique Cuenca), Juan Gabriel, Amalia Mendoza and Los Rebeldes del Rock. In 1971 she began a successful season at the El Clóset nightclub, where she shared top billing with the vedette Olga Breeskin.
