A Vedic Word Concordance (Sanskrit: Vaidika-Padānukrama-Koṣa) is a multi-volume concordance of the corpus of Vedic Sanskrit texts. It has been under preparation from 1930 and was published in 1935–1965 under the guidance of Viśvabandhu Śāstrī (1897–1973), with an introduction in Sanskrit and English. It aims to be "a universal vocabulary register" of "Vedic works, with complete textual reference and critical commentary bearing on phonology, accent, etymo-morphology, grammar, metre, text-criticism, and Ur-Aryan philology".
