Jules Émile Jeanneney (6 July 1864–27 April 1957) was a French lawyer and politician.
At the urging of René Waldeck-Rousseau Jeanneney entered politics in 1896 when he was elected mayor of Rioz.
As President of the Senate, Jeanneney led the debate on 10 July 1940 which resulted in the granting of extraordinary powers to Marshal Philippe Pétain and the creation of the Vichy Regime.
Jeanneney accepted these results rather than seeking them and along with Édouard Daladier protested at the use Pétain made of his powers.
Jeanneney served as Minister of State with responsibility for reforming the administration in Charles de Gaulle's Provisional Government from 1944 to 1945.
