El premio mayor, is a Mexican telenovela produced by Emilio Larrosa and written by Verónica Suárez and Alejandro Pohlenz.

Huicho Domínguez (Carlos Bonavides), an uneducated, womanizing family man with two children in working-class Mexico, wins the grand prize jackpot ("el premio mayor") in the national lottery.

He and his family subsequently move into a large mansion and attempt to adjust to the newfound fame and customs associated with the upper class.

Together with his sister-in-law and mistress Antonia (Lorena Herrera), who is Lorenzo's wife, and Sergio's daughter Deborah (Sussan Taunton), they are responsible for countless misdeeds, including making Jorge lose his family.

When Huicho's affairs come to light, mainly due to the sensual and interested Consuelo (Martha Julia), Lorenzo admits his own feelings for Rebeca, leading to devastating family conflicts that will shake the protagonists' faith in money as the solution to their problems.
