Pelagophyceae is a class of heterokont algae. It is the sister group of the Dictyochophyceae.
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.
The class contains 13 genera, three families and two orders (2017):

Family Pelagomonadaceae Andersen & Saunders 1993
genus Ankylochrysis Billard 1995
