Felix Antoine Philibert Dupanloup (January 3, 1802-October 11, 1878) was a French ecclesiastic. In ecclesiastical policy his views were moderate. Both before and during the First Vatican Council, he opposed the definition of the dogma of papal infallibility as inopportune, but after the definition was among the first to accept the dogma. Dupanloup died on October 11, 1878, at the chateau of La Combe-de-Lancey.
