The Anatinae is one of the subfamilies of the family Anatidae, which includes the swans, geese and ducks.

The Anatinae subfamily contains three groups of ducks:

• The dabbling duck group, of worldwide distribution, include usually 8 genera and some 50-60 living species. Salvadori's Teal and the Crested Duck are sometimes separated from Anas in monotypic genera.

• The 3 known genera and 4 known species of moa-nalos are all extinct. They formerly occurred on the Hawaiian Islands and were derived from dabbling ducks.

• 16 living or recently extinct species of diving ducks, of worldwide distribution, in presently 3 genera; Marmaronetta was formerly included with the dabbling ducks but is now treated here. Phylogenetic analysis of the probably extinct Pink-headed Duck, previously treated separately in Rhodonessa, has suggested that it belongs into Netta (Livezey, 1998), but this approach has been questioned (Collar et al., 2001). Molecular studies, which would probably resolve this question, have not been conducted to date.
