Charlemagne Émile de Maupas (8 December 1818 – 19 June 1888) was a French lawyer and politician who was head of the Parisian Police during the critical period when Napoleon III seized power in the coup of 2 December 1851.

Charlemagne Émile de Maupas was born in Bar-sur-Aube, Aube, on 8 December 1818.

[3] On 27 October 1851 Louis Napoleon appointed de Maupas to police headquarters in Paris.

His preferred approach would have been to deploy the army in force in Paris to deter any attempt at resistance.

[3] In his first proclamation he warned the people of Paris not to resist in face of inflexible force, and that night arrested all who seemed most hostile to the coup.

He took vigorous measures to arrest opponents of the regime, including several publicists whom he had deported to Africa.
