Alburnus danubicus 1s an extinct species of ray-finned fish belonging to the family Leuciscidae, which includes the minnows, daces and related fishes It was known from coastal lakes in Romania and River Danube in Romania and Bulgaria. It is extinct and has not definitely been recorded since 1943.
In 2019, a somewhat mysterious specimen was caught from River Danube, at Petrovaradin, Serbia. It might have been Alburnus danubicus, falsifying its status as an extinct species. Alternatively, it might have been an individual of Alburnus mento that moved down on the river very far from its native area in Upper Austria. The specimen was released alive after photography.{{Cite web |url=http://haltanitarsasag.hu/kep/q365.jpg |title=Photos of the 2019 specimen |access-date=2019-06-22 |archive-date=2021-12-21 |archive-url=https://web.archive.org/web/20211221154202/http://haltanitarsasag.hu/kep/q365.jpg |url-status=dead }}

Alburnus danubicus was first formally described in 1909 by the Romanian zoologist Grigore Antipa with its type locality given asseveral localities in the Danube Delta of Romania. This taxon was regarded as a synonym of the Danube bleak (A. chalcoides) or of the lake bleak (A. mento) but is now thought to have been a valid species.{{Cof genus|genus=Alburnus|access-date=4 April 2025}} This species is classified as a member of the genus Alburnus, a genus in which many of the fishes share the English common name of bleak, within the subfamily Leuciscinae of the family Leuciscidae.{{Cof family|family=Leuciscinae|access-date=4 April 2025}}
Alburnus danubicus belongs to the genus Alburnus a name derived from the Latin for whitefish but it also refers to the bleak, a name which means pale in English, in reference to the pale non lustrous colour of A. alburnus. The specific name, danubicus, means "belonging to the Danube", this taxon originally has been described as a variety of the Danube bleak found in the Danube Delta.{{cite web |url=https://etyfish.org/leuciscinae/ |title=Family LEUCISCIDAE: Subfamily LEUCISCINAE Bonaparte 1835 (European Minnows)|author=Christopher Scharpf |date=8 April 2024 |access-date=4 April 2025 |work=The ETYFish Project Fish Name Etymology Database |publisher=Christopher Scharpf}}
