Vinialesaurus is a genus of plesiosaur from the Late Jurassic (Oxfordian) Jagua Formation of Pinar del Río, Cuba.

The combinatio nova of the type species is Vinialesaurus caroli, first described as the subspecies Cryptocleidus?

cuervoi caroli by Ricardo De la Torre and Luis Rojas in 1949 under the holotype MNHNCu P 3008,[1] and redescribed by Zulma Gasparini, Bardet and Iturralde in 2002.

The authors of the 2002 paper considered Vinialesaurus distinct enough from Cryptocleidus to warrant its own genus, but it was a cryptoclidid.

The specific name honours the discoverer, Carlos de la Torre y Huerta.
