Gasparinisaura (meaning "Gasparini's lizard") is a genus of herbivorous ornithopod dinosaur from the Late Cretaceous.

The type species, Gasparinisaura cincosaltensis, was named and described in 1996 by Rodolfo Coria and Leonardo Salgado.

[1] The holotype, MUCPv-208, was uncovered in 1992 in a layer of the Anacleto Formation, dating from the early Campanian, about 83 million years old.

The tail featured low plate-like triangular chevrons that were expanded towards the back, which is unique in the Euornithopoda.

[1] A phylogenetic analysis included in the description of the Antarctic ornithopod Morrosaurus shows that the latter and Gasparinisaura are part of Elasmaria, a clade of hypsilophodonts known from South America, Antarctica and maybe Australia.
