Diplocheilichthys jentinkii is a species of freshwater ray-finned fish belonging to the family Cyprinidae, the carps, barbs, minnows and related fishes. This species was first formally described in 1904 as Osteochilus jentinkii by the Dutch ichthyologist Canna Maria Louise Popta with its type locality given as the Bongon River in the Mahakam River basin in eastern Borneo. The specific name honours the Dutch zoologist Fredericus Anna Jentink who was the curator of the Rijksmuseum van Natuurlijke Historie, Leiden, and edited the journal in which Popta published her description.{{cite web |url=https://etyfish.org/labeoninae/ |title=Family CYPRINIDAE: Subfamily LABEONINAE Bleeker 1859 (Labeos) |date=15 November 2024 |work=The ETYFish Project Fish Name Etymology Database |author=Christopher Scharpf |access-date=19 December 2024 |publisher=Christopher Scharpf}} This fish is endemism to Borneo where it occurs in the upper reaches of rivers in the Kapuas River basin in West Kalimantan, Indonesia, and in Sarawak, East Malaysia.
