Václav Klaus (Czech pronunciation: [ˈvaːtslaf ˈklaus]; born 19 June 1941 in Prague) is the second President of the Czech Republic (since 2003) and a former Prime Minister (1992–1997).

An economist, Klaus was the principal co-founder of the Civic Democratic Party, the Czech Republic's largest center-right political party. Klaus is a eurosceptic, but he reluctantly endorsed the Lisbon treaty as President of his country. He has been called the "Margaret Thatcher of Central Europe".
