Bennelongia is a genus of ostracod crustaceans in the family Cyprididae.

It is probably endemic to Australia and New Zealand,[1] and is predicted to be highly diverse.

The genus was described in 1981 and named after Woollarawarre Bennelong, the first aboriginal to have a long association with the early European settlers of Australia.

[1][3] Bennelongia may be the last true descendant genus of the Mesozoic (and now extinct) lineage of Cypridea, which was a dominant lineage of ostracod in non-marine waters in the Cretaceous.
