"Messor" is a myrmicine genus of ants with more than 100 species, all of which are harvester ants; the generic name comes from the Roman god of crops and harvest, Messor. The subterranean colonies tend to be found in open fields and near roadsides, openings are directly to the surface. The "Vessomessor" genus was recently added to messor adding 8 more species.

Colonies can achieve huge sizes and are notable for their intricately designed granaries in which seeds are stored in dry conditions, preventing germination. The structure of Messor spp. nests is complex and the genus on the whole is one of very accomplished architects.

Messor spp. are polymorphic and have a distinct caste of macrocephalic dinoergates whose role is of carrying and cutting the large seeds which comprise much of the colonies' subsistence.

Equipped with a tough shining cuticle, Messor spp. are slow moving and form long, seed-carrying runs. Colonies tend to be monogynous and are founded by a single queen alone.
