The greylag is the largest and bulkiest of the grey geese of the genus ''Anser''. It has a rotund, bulky body, a thick and long neck, and a large head and bill.

It has pink legs and feet, and an orange or pink bill. It is 74 to 91 centimetres long with a wing length of 41.2 to 48 centimetres. It has a tail 6.2 to 6.9 centimetres, a bill of 6.4 to 6.9 centimetres long, and a tarsus of 7.1 to 9.3 centimetres. It weighs 2.16 to 4.56 kilograms, with a mean weight of around 3.3 kilograms. The wingspan is 147 to 180 centimetres. Males are generally larger than females, with the sexual dimorphism more pronounced in the eastern subspecies ''rubirostris'', which is larger than the nominate subspecies on average.

The plumage of the greylag goose is greyish-brown, with a darker head and paler belly with variable black spots. Its plumage is patterned by the pale fringes of its feathers. It has a white line bordering its upper flanks. Its coverts are lightly coloured, contrasting with its darker flight feathers. Juveniles differ mostly in their lack of a black-speckled belly.

It has a loud cackling call, ''HOOOOOONK!'' or ''GAAA!'', like the domestic goose.

It was in pre-Linnean times known as the wild goose. This species is the ancestor of domesticated geese in Europe and North America. Flocks of feral birds derived from domesticated birds are widespread.

This species is found throughout the Old World, apparently breeding where suitable localities are to be found in many European countries, although it no longer breeds in southwestern Europe. Eastwards, it extends across Asia to China. In North America, there are both feral domestic geese, which are similar to greylags, and occasional vagrants.

In Great Britain, their numbers had declined as a breeding bird, retreating north to breed wild only in the Outer Hebrides and the northern mainland of Scotland. However, during the 20th century, feral populations have been established elsewhere, and they have now re-colonised much of England. These populations are increasingly coming into contact. The breeding habitat is a variety of wetlands including marshes, lakes, and damp heather moors.

In Norway, the number of greylag geese is estimated to have increased three- to fivefold during the last 15–20 years. As a consequence, farmers' problems caused by goose grazing on farmland has increased considerably. This problem is also evident for the pink-footed goose.

The geese are generally migratory, moving south or west in winter. Scottish breeders, some other populations in northwestern Europe, and feral flocks are largely resident. This species is one of the last to migrate, and the "lag" portion of its name is said to derive from this lagging behind other geese.
