Kiwa is a genus of marine decapods living at deep-sea hydrothermal vents and cold seeps. The animals are commonly referred to as "yeti lobsters" or "yeti crabs", after the mythical yeti. The genus is placed in its own family, Kiwaidae, in the superfamily Chirostyloidea.

Two species have been described: Kiwa hirsuta discovered in 2005, and Kiwa puravida, discovered in 2006. A third species, known colloquially as the "Hoff crab", has been discovered on the East Scotia Ridge, but is as yet undescribed.
