Isabel is a Spanish historical fiction television series, directed by Jordi Frades and produced by Diagonal TV for Televisión Española.

The first season chronicles the period between 1461 and 1474: from the end of her childhood to her marriage with Ferdinand of Aragon and her difficult arrival to the Crown.

The series was initially expected to debut on 30 January 2012, but a budget cut for TVE postponed the premiere.

Jordi Frades, director of the series, also directed the film, and Rodolfo Sancho (as King Ferdinand), Irene Escolar (as Joanna the Mad), Raúl Merida (as Philip the Handsome) and Eusebio Poncela (as Francisco Jiménez de Cisneros) reprised their roles.

The film served as the link between Isabel and the series Carlos, rey emperador, which is based upon the reign of Charles I, Isabella's grandson.
