潜鸭属（Aythya）是鸭科下的一属。

于土耳其发现早更新世的化石，有可能是潜鸭属的古亚种。

中新世的"Aythya" arvernensis现已被编入Mionetta中，而"Aythya" chauvirae似乎包含了两个物种，但最少有一种已肯定不是潜鸭属。

Aythya is a genus of diving ducks. It has twelve described species. The name Aythya comes from the Ancient Greek word αυθυια, aithuia, which may have referred to a sea-dwelling duck or an auklet.

Aythya shihuibas was described from the Late Miocene of China. An undescribed prehistoric species is known only from Early Pleistocene fossil remains found at Dursunlu, Turkey; it might however be referrable to a paleosubspecies of an extant species considering its age (see also Greater scaup).
