Thierry Breton (French pronunciation: [tjɛʁi bʁətɔ̃]; born 15 January 1955) is a French business executive, politician, writer and former Commissioner for Internal Market of the European Union from 2019 to 2024. Breton was vice-chairman and CEO of Groupe Bull (1996–1997), chairman and CEO of Thomson-RCA (1997–2002) and chairman and CEO of France Télécom (2002–2005). In 2005 he entered politics serving as Minister of Economy, Finance and Industry (2005–2007) in the governments of Prime Ministers Jean-Pierre Raffarin and Dominique de Villepin, during the presidency of Jacques Chirac. From 2007 to 2008 he was a professor at Harvard Business School before joining group Atos from 2009 to 2019 as its CEO.
From 2019, Breton served as the European Commissioner for Internal Market under the presidency of Ursula von der Leyen, an appointment that met with controversy, as he was considered by anti-corruption association Anticor to be at serious risk of conflicts of interest over his previous posts at France Télécom and Atos. Breton resigned from the position in 2024.
