Galeommatoidea a superfamily of bivalves classified in the monotypic order Galeommatida.

Galeommatoids exhibit symbiotic relationships with many different groups of benthic and burrowing invertebrates.

[5] The monophyly of Galeommatoidea is strongly supported by molecular phylogenetic analyses.

[1][4] However, the internal classification of Galeommatoidea is controversial, and it has been divided into various poorly-defined families that may not be monophyletic.

[4] As of 2010, it was estimated that Galeommatoidea contained approximately 500 species in 100 genera.
