This list of gastropods described in the 2000s is a list of new species (and other new taxa) of gastropod mollusks (i.e. snails and slugs from saltwater, freshwater, and land) that were described for the first time in the scientific literature during the time span from the year 2000 to the year 2009. The number of newly described gastropod is enormous. For example, in A Database of Western Atlantic Marine Mollusca (this includes all classes of molluscs, not only gastropods) there are 718 new records from this time span, which total unfortunately includes a number of synonyms.
