Trinisaura is an extinct genus of ornithopod dinosaur known from the lower levels of the Late Cretaceous Snow Hill Island Formation of James Ross Island, Antarctica. It contains a single species, Trinisaura santamartaensis. It lived 70-65 mya.
The species was named by Rodolfo Aníbal Coria e.a. in 2013. The generic name honours the geologist Trinidad Diaz. The specific name refers to the Santa Marta Cove site where the specimen was found by Coria and Juan José Moly in 2008. The holotype, MLP-III-1-1, consists of a partial skeleton lacking the skull, of a subadult individual about 1.5 metres in length.
