Carlos Emilio Gaviria Díaz (born 8 May 1937) is a Colombian lawyer, professor and politician. He served as the 5th Chief Magistrate of the Constitutional Court of Colombia, where he served as a Magistrate from 1993 to 2001. After retiring from the Court, he went into politics becoming a Senator of Colombia in 2002, and running for President as an Alternative Democratic Pole candidate in the 2006 presidential election, ultimately losing to ex-president Álvaro Uribe Vélez, who was seeking his second term in office.
Gaviria began his judicial career the same year he graduated from university in 1961 when he was appointed Municipal Promiscuous Judge of Rionegro, but he returned to Medellín when he was named Professor at the University of Antioquia. In 1992 Gaviria was nominated as part of the Council of State's ternary list presented to the Senate as part of the election process for new members of the Constitutional Court, a High Court of the Judicial Branch of Colombia recently created by the Colombian Constitution of 1991. Gaviria was successfully confirmed by the Senate, and took office on 1 March 1993 as part of the first permanent Constitutional Court for a constitutional term of 8 years. On 1 March 1996 Gaviria was elected Chief Magistrate of the Constitutional Court, replacing José Gregorio Hernández Galindo from 1 March 1996 to 1 March 2001, when Gaviria finished his term as Magistrate in the court, and was replaced by Alfredo Beltrán Sierra as Chief Magistrate.
In 2002, he was elected Senator of Colombia representing the leftist political formation, the Social and Political Front, after achieving the fifth-highest voting result in the elections. He ran for the presidency of Colombia for the 2006–2010 term, as the candidate of the Alternative Democratic Pole, after winning the bloc nomination over Antonio Navarro. Polls in late April 2006 placed Gaviria in second place after incumbent President Álvaro Uribe, leaving behind the Liberal Party's Horacio Serpa, who is running for president for the third consecutive time. He lost to President Uribe in the May 2006 election by a margin of 62% to 22%.
