Ligabuesaurus is a genus of dinosaur from the Early Cretaceous (Aptian to Albian stage, 100 to 125 million years ago). It was a basal titanosaurid sauropod which lived in what is now Argentina. The type species, Ligabuesaurus leanzai, was described by Jose Bonaparte, Gonzalez Riga, and Sebastian Apesteguia in 2006, based on a partial skeleton. The specific name, leanzai, is dedicated to the geologist Dr. Hector A. Leanza, who discovered the skeleton.
