Aralosaurus (meaning "Aral Sea lizard", because it was found in the Aral Sea - Greek sauros = lizard) was a genus of hadrosaurid dinosaur which lived during the Late Cretaceous of what is now Kazakhstan. Aralosaurus was characterized by a small, bony peak on its nose, much like its relatives Maiasaura and Gryposaurus. It was described by Soviet paleontologist A. Rozhdestvensky in 1968.
