Ligabuesaurus is a genus of somphospondylan sauropod dinosaur from the Early Cretaceous that lived in what is now Argentina.

The type species, Ligabuesaurus leanzai, was described by Jose Bonaparte, Gonzalez Riga, and Sebastián Apesteguía in 2006, based on a partial skeleton with skull, holotype MCF-PHV-233.

[1] The generic name, Ligabuesaurus, honors Giancarlo Ligabue, while the specific name, leanzai, honors the geologist Dr. Héctor A. Leanza, who discovered the skeleton in the Lohan Cura Formation.

[3] A third skeleton was recovered but not referred due to a lack of overlapping material.
