Emmanuelle Mignon (born 26 April 1968) served as cabinet director for French president Nicolas Sarkozy between May 2007 and July 2008.
She also studied at the ENA school (Ecole nationale d’administration) for high-level civil servants and graduated at the top of her class in 1995.
In 2015 after being admitted to the Paris Bar, she joined the Public Regulatory Environment department of August Debouzy as a partner.
On 22 January 2022, she was sentenced to 6 months in prison with a suspended sentence for having "intentionally sacrificed respect for the republican rule of law that she was supposed to embody in her capacity as Chief of Staff to the President of the Republic to the satisfaction of private interests expressed by two people close to the Head of State".
Mignon and three co-defendants, former Nicolas Sarkozy chief of staff Claude Gueant, writer and one-time Sarkozy advisor Patrick Buisson and former pollster and consultant Pierre Giacometti, were found guilty of polling fraud involving allegations that they misused public money while ordering public opinion polls worth a combined 7.5 million euros ($8.7 million) during the course of Sarkozy's presidency.
