Aphanizocnemus is an extinct genus of varanoid lizard from Lebanon. It is a marine lizard that lived during the Late Cretaceous. It is often classified in the family Dolichosauridae as a close relative of snakes, although some studies have placed it as an even closer relative to snakes than dolichosaurids. Only one species of Aphanizocnemus is known, the type species A. libanensis. A. libanensis was named in 1997 on the basis of a single complete skeleton.
