La Dueña (English title: Lady Owner) is a Mexican telenovela produced by Florinda Meza for Televisa in 1995.

Life seems to smile at Regina Villarreal (Angélica Rivera), a young and beautiful woman who inherits a fortune from her deceased parents.

Regina lives with her aunt, Berenice (Norma Herrera), whom she loves as if she were her own mother, her unbearable cousin, Laura (Cynthia Klitbo), and her inseparable nanny, Martina (Josefina Echánove).

On her wedding day, Mauricio leaves Regina at the altar, a fact which shatters her heart and makes it grow cold and bitter.

Laura has fallen in love with José María; because of it, Regina will become once again a target for her cousin, even though this time "La Dueña" will not let anyone steal her beloved's heart from her.
