Near threatened (NT) species do not currently qualify for critically endangered (CR), endangered (EN) or vulnerable (VU) status, but are likely to qualify for a threatened category in the near future, or are already close to qualifying.

In July 2016, the International Union for Conservation of Nature (IUCN) listed 1105 near threatened invertebrate species.[1] Of all evaluated invertebrate species, 6.1% are listed as near threatened. The IUCN also lists 15 invertebrate subspecies as near threatened.
