The Camerata or camerate crinoids are an extinct subclass of Paleozoic stalked crinoids. They originated in the Middle Ordovician and became extinct in the end-Permian mass extinction, and reached their maximum diversity during the Mississippian.

Anatomically, they are distinguished by:

fused junctions between the plates of the cup

brachial plates incorporated into the cup

tegmen forming a rigid roof over the mouth

no less than ten and sometimes a very large number of free arms, often pinnulate
