Kryptohadros is an extinct genus of hadrosauroid ornithopod dinosaur known from the Late Cretaceous Densuș-Ciula Formation of Romania. The genus contains a single species, Kryptohadros kallaiae, known from a partial skull and skeleton. Phylogenetic analyses revealed Kryptohadros is closely related to the coeval Transylvanian Telmatosaurus and the Italian Tethyshadros, together forming a group of southeastearn European-endemic taxa, called the Telmatosauridae. Kryptohadros is the second named non-hadrosaurid hadrosauroid from the Hațeg Basin, following Telmatosaurus, which was named by Franz Nopcsa in 1903.
