Allopleuron (meaning "other side") is a genus of extinct sea turtle, which measured 2-to-2.5-metre (6 ft 7 in to 8 ft 2 in) long in life. The type species is Allopleuron hofmanni. It is a basal member of the clade Pancheloniidae, closely related to Protosphargis. Similar to Protosphargis, it was characterized by shell reduction.
