Hadrosaurus (Grec : ἁδρός, hadros + σαυρος, sauros = lézard robuste) est un genre douteux de la famille des hadrosauridés, ou « dinosaures à bec de canard ». En 1858, un squelette d'un spécimen du genre est découvert en Amérique du Nord et devient le premier squelette de dinosaure jamais reconstitué.
