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. salgueiroensisSchultze, 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]
