Obdulio Jacinto Muiños Varela (; September 20, 1917 — August 2, 1996) was a Uruguayan football player. He was the captain of the Uruguayan national team that won the 1950 World Cup after beating Brazil in the decisive final round match popularly known as the "Maracanazo". He was nicknamed "El Negro Jefe" (The Black Chief) because of his dark skin and the influence he had on the pitch, especially during the unlikely victory over Brazil. He was of African, Spanish and Greek ancestry. Commonly regarded as one of the greatest classic holding midfielders, Varela was adept in defence and was renowned for his tenacity and leadership. He is regarded as one of the greatest captains in football history, and "he remains one of the biggest sporting heroes in Uruguay".
