Rappemonada ili Rappephyceae je grupa fotosintetskih morskih i slatkovodnih protista, čiji je filogenetski položaj neizvjestan.[1][2] Ćelije su im dužine 5-7 µm i sadrže 2-4 plastida sa hlorofilom a. Poznate su samo iz uzoraka iz prirode, pa su slabo okarakterizirane i još uvijek nisu opisane vrste ili rodovi.

Filogenetske analize ribosomne DNK (rDNK) u plastidima sugeriraju da ova grupa predstavlja evolucijsku granu koja se nalazi između algi Cryptophyta i Haptophyta. Studije DNK su također otkrile da su široko rasprostranjene u sjevernom Atlantiku, sjevernom [Pacifik]]uTihom i u evropskim slatkovodnim staništima. S druge strane, kvantitativne analize lančana reakcija polimeraze (PCR pokazuju da je Rappemonada obično rijetka, ali može formirati cvjetanje algi

Klasifikacija prema Adl et al., Rappemonada smatra nesigurnom grupom za taksonomsko svrstavanje.[3][4][5] U međuvremenu, Cavalier-Smith stavlja Rappephyceae unutar Hacrobia.[6][7]
