None that Ive heard of, but there is some land crabs. But I think they even need some access to some water, and the water is usually brackish.

Yes, there are many true freshwater crabs ... including fully aquatic species that don't need land access. They show up less regularly than red-claws (one or a few species of SE Asian Sesarmids) and fiddlers (Uca spp.), both of which can tolerate freshwater but really need brackish and semi-aquatic conditions for long-term survival.

Here's one such fully aquatic freshwater species, Potamonautes orbitospinus, the Malawi blue crab (from Lake Malawi, of course):



Cardisoma spp. like this C. armatum (rainbow, Halloween, patriot, moon crabs) live in freshwater, but do best with a land area:



See this page for the species you'll most likely encounter in stores.
