Olisthodiscus is a genus of heterokont algae, present in marine or brackish waters. It is the only genus in the family Olisthodiscaceae, the order Olisthodiscales, and the class Olisthodiscophyceae. After a long history of controversial classifications, in 2021 it was recognized as a phylogenetically distinct lineage from the rest of ochrophyte classes.
