Dianmeisaurus is an extinct genus of pachypleurosaur from the Middle Triassic Guanling Formation in China. The type species is D. gracilis.[1] An additional species, D. mutaensis, was named in 2024 based on a small skeleton likely belonging to an immature individual.[2]

In their 2024 description of Dianmeisaurus mutaensis, Hu, Li & Liu recovered the two species of Dianmeisaurus as the sister taxon to Panzhousaurus in a clade of basally-branching pachypleurosaurs. In their analyses, they recovered the Pachypleurosauria as the sister taxon to the Nothosauroidea. The results of their phylogenetic analyses are shown in the cladogram below:[2]
