Microcoelus (meaning "small hollow") is a dubious genus of small titanosaurian sauropod dinosaur from the Bajo de la Carpa Formation, Argentina.[1][2] It is known from only a single dorsal vertebra. A left humerus was formerly referred to this species, but it is now considered to belong to Neuquensaurus.[1] This species is considered a nomen dubium.[1]

It was described by British paleontologist Richard Lydekker in 1893.[3]
