Irma Consuelo Cielo Serrano Castro (9 December 1933 – 1 March 2023), better known simply as Irma Serrano, was a Mexican singer, actress, and politician, widely known by the nickname “La Tigresa.” Born in Comitán de Domínguez in Chiapas, she rose to prominence in the 1960s as a performer of ranchera and corrido music and developed a parallel screen career spanning Mexican cinema from the early 1960s onward.

In music, Serrano recorded and performed extensively in traditional Mexican popular styles; sources note a professional takeoff in the early 1960s, including work associated with Columbia Records.
