Los opistobranquios (Opisthobranchia) o babosas de mar son una infraclase de moluscos gasterópodos. El nombre deriva del griego opisthen, detrás, y significa branquias atrás, al contrario de los Prosobranchia (del griego proso, adelante) que significa branquias adelante. Su masa visceral presenta solo una torsión de 90º (y no de 180º) respecto al conjunto cabeza-pie, lo que los distingue de los prosobranquios. Son exclusivamente marinos y su concha está reducida o ausente.

Opisthobranchs () is a now informal name for a large and diverse group of specialized complex gastropods which used to be united in the subclass Opisthobranchia. That taxon is no longer considered to represent a monophyletic grouping.
Euopisthobranchia is a taxon containing a revised collection of opisthobranchs, and that taxon is considered monophyletic. Euopisthobranchia does not include some "traditional" opisthobranchs such as the Sacoglossa and the Acochlidiacea. The subclass Heterobranchia now contains all the species which used to be assigned to Opisthobranchia, plus all the species in the Pulmonata.
