Jules Émile Jeanneney (6 July 1864–27 April 1957) was a French lawyer and politician.
Jules Jeanneney was born in Besançon in the department of Doubs. His mother died soon after his birth, leaving his father, an auctioneer, to raise the child. Jeanneney said that he felt that his mother's death affected him greatly in later life. He studied law at the Sorbonne and practised as a lawyer.
Jeanneney was elected vice-president in 1924, then he headed the important Finance committee until 1932 when he was elected President of the Senate to replace Albert Lebrun. 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.
