Arthrodytes is an extinct genus of penguins which contains a single species, whose remains have been recovered from the San Julian Formation (Late Eocene to Early Oligocene) of Patagonia.^[1] Other authors report a younger age for the fossils recovered from the Early Miocene Gaiman and Monte León Formations.^[2]

Together with the related genus Paraptenodytes, they form the subfamily Paraptenodytinae, which is not ancestral to modern penguins.^[1]
