Rosa María Juana Martínez, better known by the stage name Mirtha Legrand (born 23 February 1927 in Villa Cañás, Santa Fe Province) is an Argentine actress and television personality and twin sister of the actress Silvia Legrand.

The future Mirtha Legrand was born in Villa Cañás, a town in the province of Santa Fe located some 200 km from Rosario. Her parents were both Spanish immigrants. In 1934 her parents separated. Her mother relocated to Rosario to ensure a better education for her three children, while her father remained in Villa Cañás.

In Rosario, Rosa María Juana and her twin sister María Aurelia took basic courses at the Municipal Theater. After the death of their father in 1936, the family relocated permanently to Buenos Aires, to the barrio of La Paternal. There they lived in poverty, mitigated by sporadic employment, until in 1939 the sisters were offered small roles in a film starring Niní Marshall which would be released in 1940 under the title Hay que educar a Niní.

The Martínez sisters' next film together was Novios para las muchachas in 1941. Mirtha's first leading role came later that year in Los martes, orquídeas. The same year her mother would be contacted by a well-known film industry figure, Ricardo Cerebello, who offered to represent the sisters. It was Cerebello who devised the stage names Mirtha and Silvia Legrand.
