Pelagophyceae is a class of heterokont algae. It is the sister group of the Dictyochophyceae.[2]

All known species are marine. They can be single-celled (coccoid or flagellate), palmelloid or filamentous. Some members (Pelagomonas) belong to picoplankton, and some other (Sarcinochrysis) are macroscopic attached organisms.[3]

The class contains 13 genera, 3 families and 2 orders (2017):[4][5]

It is expected that molecular studies will add more species to this list.[3]
