Volgatitan is a genus of sauropod dinosaur from the Early Cretaceous of the Ulyanovsk Oblast, Russia. The type and only species is Volgatitan simbirskiensis, known from seven caudal vertebrae from a single individual. It was initially described as a titanosaur related to Lognkosauria, but a later study suggests it may instead be a member of Mamenchisauridae. It was first described in November 2018 by Russian palaeontologists Alexander Averianov and Vladimir Efimov. It is estimated to have weighed about 17.3 metric tons.

Skeletal restoration of the titanosaurian sauropod Volgatitan. Only seven caudal vertebrae are known, and only six were well-preserved enough to be figured. A modified silhouette of the 6th vertebra is standing in for the seventh. The first vertebra does appear to actually be the first in the caudal series, although the precise locations of the other vertebrae are unknown. The silhouette is based on Mendozasaurus. The human silhouette is from File:Silhouette of man standing and facing forward.svg. The scale of the image at full size is 1px=1mm. References: (2018).
