Dialipina is an extinct genus of prehistoric marine bony fish from the Early Devonian.[1][2] It contains two species, both known from the high Arctic of Asia and North America. It was initially thought to be and sometimes still is treated as an early, basal actinopterygian,[3][4][5] but recent phylogenetic analyses suggest that it may instead be a stem-osteichthyan.[6][7]

The following species are known:[1]
- †D. markae Schultze, 1992 - Lochkovian of Kotelny Island, Russia
- †D. salgueiroensis Schultze, 1968 (type species) - Emsian of the Northwest Territories, Canada (Bear Rock Formation)
The early Devonian stem-gnathostome Janusiscus was described from remains from the Siberian mainland that were previously attributed to D. markae.[7]
