Marnaviridae is a family of RNA viruses in the order Picornavirales. Seaweed and Heterosigma akashiwo algae serve as natural hosts. There is only one genus (Marnavirus) and one species in this family: the type species Heterosigma akashiwo RNA virus (HaRNAV).

Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. The virus exits the host cell by tubule-guided viral movement.
