Lilia Guadalupe Mendiola Mayares (born December 12, 1949), better known by her stage name Lyn May, is a Mexican vedette, exotic dancer and actress.

She would eventually go on to work as a waitress in a restaurant where she met her first husband, an American sailor 30 years her senior, with whom she settled in Mexico City.

After five years of marriage and the birth of their two daughters, Lilia separated from her husband alleging domestic violence and sexual abuse.

Eventually she worked at the Tropicana cabaret in Acapulco, where she alternated with the popular Mexican comedian Germán Valdés "Tin Tan".

After her successful season with Tin Tan, Lilia traveled to Mexico City, where television presenter Raul Velasco hired her as a dancer in the program Siempre en Domingo.

In 1974, filmmaker Alberto Isaac chose Lyn as one of the main protagonists of the famous film Tívoli, which portrays with nostalgia the nocturnal atmosphere of Mexico City in the 1940s and 1950s.

She currently works as a Tahitian dance instructor at the Plaza Caribe Hotel in Cancun, Mexico and gives performances on weekends in the bar of the same establishment.

In 2016, Lyn was featured in the documentary film Beauties of the Night, by the filmmaker María José Cuevas, along with other vedettes like Olga Breeskin, Rossy Mendoza, Wanda Seux and Princesa Yamal.
