Cryptochrysis is a formerly recognized genus of cryptomonads first proposed by Adolf Pascher in 1911. He initially treated it as the sole genus in family Cryptochrysidaceae, but later treated it as a member of the Cryptochrysideae subfamily of Cryptomonadaceae, along with Rhodomonas, Chroomonas, and Cyanomonas. In 1967, R.W. Butcher relegated the group to a subgenus within Chroomonas.

It is now regarded as paraphyletic, with its species now various reassigned into Pyrenomonas, Rhinomonas and Cryptomonas.
