Eduardo Alfredo Juan Bernardo Frei Ruiz–Tagle (Spanish pronunciation: [eˈðwaɾðo alˈfɾeðo ˈxwam beɾˈnaɾðo ˈfɾej rwis ˈtaɣle]; born 24 June 1942) is a Chilean politician and civil engineer who served as president of Chile from 1994 to 2000.

He attempted a comeback as the candidate of the ruling Concertación coalition for the 2009 presidential election, but was narrowly defeated.

His presidency was marked by a consolidation of Chile's transition to democracy albeit the indictment and arrest of Augusto Pinochet in his last year of government heated up national politics.

In 1958, he joined the Christian Democrat party, and in 1964 participated actively in his father's successful presidential campaign.

[4] During Frei's ternure the Laguna del Desierto territorial dispute with Argentina was solved, albeit the arbitrage favoured the Argentine position.

Since neither candidate received more than half of the total votes, a runoff election was held on Sunday, 17 January 2010.

The first preliminary results announced by the Deputy Interior Ministry at 21:00 GMT on election day gave Piñera 51.87% and Frei holding 48.12%.
