El Gran Show season 20

Season three of the 2017 edition of El Gran Show premiered on September 2, 2017.

The season was also named "La Revancha", due to the return of former participants for a new opportunity to win the competition.

On October 14, 2017, Anahí de Cárdenas and her professional dancer George Neyra were crowned champions, Vania Bludau and Oreykel Hidalgo finished second, while César Távara and Alexa Montoya finished third. In this way, Neyra became the second professional dancer two times champion, after Lucas Piró, since he also won Reyes de Show of 2015.
