Ochrophyta is a group of mostly photosynthetic heterokonts.

The classification of the group is still being worked out. Some authors (e.g., Cavalier-Smith) divide it into two subphyla, Phaeista Cavalier-Smith 1995 (comprising Hypogyristea and Chrysista in some classifications, or Limnista and Marista in others) and Khakista Cavalier-Smith, 2000 (comprising Bolidomonas and diatoms). Others prefer not to use the subphyla, listing only lower taxa (e.g., Reviers, 2002, Guiry & Guiry, 2014).
