The Anserinae is a subfamily in the waterfowl family Anatidae. It includes the swans and true geese. Under alternative systematical concepts (see e.g., Terres & NAS, 1991), it is split into two subfamilies, the Anserinae containing the geese and the ducks, while the Cygninae contain the swans.

A number of other waterbirds, mainly related to the shelducks, have "goose" as part of their name; see the family page at Anatidae and the goose page for these.

Systematics

Swans - tribe Cygnini

• Genus Cygnus - true swans

The black-and-yellow-billed swans are sometimes separated in the genus Olor.

True Geese - tribe Anserini

• Genus Anser - grey geese
• Genus Chen - white geese (sometimes included in Anser)
• Genus Branta - black geese

Unresolved

• Genus Coscoroba - Coscoroba Swan

The following two genera are distinct from other geese and often elevated to a subfamily of their own (Cereopsinae), or alternatively into the shelduck subfamily Tadorninae:

Tribe Cereopsini

• Genus Cereopsis - Cape Barren Goose
• Genus Cnemiornis - New Zealand geese (prehistoric)

There are some enigmatic subfossils of very large goose-like birds from the Hawaiian Islands which do not appear to be moa-nalos (goose-sized dabbling ducks). They cannot be assigned to any genus living today, though most if not all may be fairly close to Branta:

• Geochen rhuax - initially allied with Cereopsis, but this seems hardly correct for reasons of biogeography.
• Giant Hawaiʻi Goose, ?Branta sp.
• Giant Oʻahu Goose, Anatidae sp. et gen. indet.
