Lambert of Vignory, or Lambert II, was the bishop elect of Langres between the death of Bishop Robert in 1111 and the election of Joceran de Brancion in 1113. He is probably to be identified with the archdeacon of the same name who served Langres Cathedral in the same period. He was probably the son of Guy II, lord of Vignory, and Hildegarde. An earlier bishop, Lambert I, is sometimes (erroneously) called "Lambert of Vignory" also.
