Jules François Alexandre Joffrin (March 16, 1846 - September 17, 1890), French politician, was born at Troyes.

He served in the Franco-German War, was involved in the Commune, and spent eleven years in England as a political exile. He attached himself to the possibilist group of the socialist party, the section opposed to the root-and-branch measures of Jules Guesde. He became a member of the municipal council of Paris in 1885, and vice-president in 1888-1889.

Violently attacked by the Boulangist organs, L'Intransigeant and La France, he won a suit against them for libel, and in 1889 he contested the XVIIIe arrondissement of Paris with General Boulanger, who obtained a majority of over 2000 votes, but was declared ineligible.

Joffrin was only admitted to the Chamber after a heated discussion, and continued to be attacked by the nationalists. He died in Paris on the 17th of September 1890.
