Dendrogaster is a genus of endoparasitic crustaceans belonging to the family Dendrogastridae.

[1] Its habitat depth varies widely, ranging from the intertidal zone to approximately 2,500 m. The genus has cosmopolitan distribution.

[1] They parasitize the coelom of asteroids (sea stars).

[2][3] At present, Dendrogaster have been discovered in eighteen families of sea stars, implying a non-specific host preference.
