Microcoelus (meaning "small hollow") is a dubious genus of small titanosaurian sauropod dinosaur from the Bajo de la Carpa Formation, Argentina.

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.
