Clathrina is a genus of calcareous sponge in the family Clathrinidae.

Several species formerly in Clathrina were transferred to the newly erected genera Arturia, Ernstia, Borojevia, and Brattegardia in 2013.

[2] The name is derived from the Latin word "clathratus" meaning "latticed".

The skeleton contains spicules in the form of triactines and/or tetractines, sometimes with diactines, tripods and tetrapods as well.

The choanoderm is usually flat, never forming folds when the sponge is extended.
