Alain Madelin (born 26 March 1946, in Paris) is a French politician and a former minister of that country.
Madelin, a strong supporter of laissez-faire economics, was a candidate in the 2002 French presidential election as the leader of the Démocratie Libérale party, where he scored 3.91% on the first round. Following the election, he became a member of the Union for a Popular Movement (UMP).
He was minister of Industry in Prime Minister Jacques Chirac's cabinet from 1986 to 1988, a minister of Business in Prime Minister Édouard Balladur's cabinet from 1993 to 1995, and a minister of Economy and Finances in Prime Minister Alain Juppé's cabinet. He resigned after only four months, citing economic policy differences with Alain Juppé.
He was a member of the National Assembly from 1978 to 2007 as representative for Ille-et-Vilaine's fourth circumscription. The district includes the town of Redon, where he was mayor from 1995 until 2001.
Madelin unsuccessfully ran in 1996 for president of the Union for French Democracy (UDF), and was defeated by François Léotard. He was elected as leader of the Parti Républicain, a part of the UDF coalition, which he renamed Démocratie Libérale. In 1998, Démocratie Libérale split from the UDF. Madelin's obtained slightly less than 4% of the vote in the 2002 presidential election and merged his party into the UMP. After 2002, although his former supporter Jean-Pierre Raffarin became Prime minister, and as a result of the end of Démocratie Libérale, Madelin's influence in French national politics dwindled.
