Cristian Leonel Ramírez Zambrano (Spanish pronunciation: [ˈkɾistjan raˈmiɾes]; born 12 August 1994) is an Ecuadorian professional footballer who plays as a left-back for Ferencváros of the Nemzeti Bajnokság I.

A promising young left-back, even as to being compared to the legendary Roberto Carlos, his professional debut came on 28 August 2011, against El Nacional, fully completing everyone's expectations of his abilities on-field, and started most of his 2011 Serie A games.

He also gained a fearsome reputation, having stopped on their tracks promising young Ecuadorian talents such as Fidel Martinez and Renato Ibarra; the latter being during Ramirez' debut.

[14][15][16] On 2 April 2016, Ramírez became Hungarian League champion with Ferencvárosi TC after losing to Debreceni VSC 2–1 at the Nagyerdei Stadion in the 2015–16 Nemzeti Bajnokság I season.

[22] On 20 April 2024, the Ferencváros–Kisvárda tie ended with a goalless draw at the Groupama Aréna on the 29th match day of the 2023–24 Nemzeti Bajnokság I season[23] which meant that Ferencváros won their 35th championship.

[28] Ramírez showcased his footballing skills and mental capacity in the 2011 U-17 World Cup to successfully defend against the likes of Germany, Panama and Burkina Faso.
