Jhon Mario Ramírez (2 December 1971 – 26 June 2021) was a Colombian football manager and former player who played as a midfielder. He last worked as manager of Patriotas.
Ramírez was well known in Bogotá, where he was a fan favorite during the mid-1990s when he played for Millonarios. He also played club football for Deportivo Cali, Deportes Tolima, Independiente Santa Fe, Boyacá Chicó F.C. and Deportivo Pereira. Ramírez filed a claim against his former team Deportes Tolima, arguing that the club had cancelled his playing contract without cause. In 2008, the Supreme Court of Colombia denied Ramirez's claim for compensation.[1]
He was also part of the Colombia national team. His last game for the national team was a friendly against Norway in 1997.[2]
Ramírez died on 26 June 2021, aged 49 at San Rafael hospital in Tunja after contracting COVID-19 amid the COVID-19 pandemic in Colombia.[3]
