The Eurasian spoonbill (Platalea leucorodia), or common spoonbill, is a wading bird of the ibis and spoonbill family Threskiornithidae, native to Europe, Africa and Asia. The species is partially migratory with the more northerly breeding populations mostly migrating south for the winter.

The Eurasian spoonbill was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the current binomial name Platalea leucorodia. Linnaeus cited works by earlier authors including the description and illustration by the English naturalist Eleazar Albin that was published in 1734. Linnaeus specified the type locality as Europe but restricted it to Sweden in 1761. The genus name Platalea is Latin and means "broad", referring to the distinctive shape of the bill; the specific epithet leucorodia is from Ancient Greek leukerodios meaning "spoonbill", itself derived from leukos, "white" and erodios "heron". A molecular phylogenetic study of the spoonbills based on mitochondrial DNA found that the Eurasian spoonbill is sister taxon to a clade containing the royal and black-faced spoonbills. In England it was traditionally known as the "shovelard", a name later used for the northern shoveler.

Three subspecies are recognised. These are listed below with their breeding ranges.

The royal spoonbill (Platalea regia) was formerly considered as a subspecies. Birds in Asia were sometimes separated as P. l. major.

This species is almost unmistakable in most of its range. The breeding bird is all white except for its dark legs, black bill with a yellow tip, and a yellow breast patch like a pelican. It has a crest in the breeding season. Non-breeders lack the crest and breast patch, and immature birds have a pale bill and black tips to the primary flight feathers. Unlike herons, spoonbills fly with their necks outstretched. The Eurasian spoonbill differs from the African spoonbill with which in overlaps in winter, in that the latter species has a red face and legs, and no crest.

They are mostly silent. Even at their breeding colonies the main sounds are bill snapping, occasional deep grunting and occasional trumpeting noises.

This species is found widely in Europe, Asia and Africa. In Europe, it breeds from the United Kingdom and Portugal in the west, locally through the continent; ranging north to Denmark and east to the Balkans and the Black Sea. In Asia, it breeds in a broad band across the central part of the continent, from the Black Sea to the Korean Peninsula, as well as Kuwait, southern Iraq, Iran, southern Pakistan, India and Sri Lanka. In Africa, it breeds locally in coastal Mauritania, but more widely along the Red Sea and Gulf of Aden coasts. Whereas those breeding in warmer parts of Asia, in Africa and the Iberian Peninsula are resident or only move locally, more northern breeders generally migrate south to winter in southwestern Europe, the northern half of Africa or warm parts of Asia. However, some northern birds do remain in the general region during the winter, including the United Kingdom, the Low Countries and France. Outside of its normal range, they have been recorded as a rare vagrant in Ireland, Belarus, Brazil, Trinidad and Tobago, the Canary Islands, Greenland, Nigeria, Uganda, Guadeloupe, Martinique, Barbados, and Saint Lucia.

Eurasian spoonbills show a preference for extensive, shallow wetlands with muddy clay or fine, sandy beds. They may inhabit any type of marsh, river, lake, floodplain or mangrove swamp, be it fresh, brackish or saline water. They are especially attracted to locations with undisturbed islands for nesting and habitats with dense, riparian-emergent vegetation (e.g. reedbeds) and scattered trees/shrubs, especially willow Salix spp., oak Quercus spp. or poplar Populus spp. Eurasian spoonbills may also frequent sheltered marine habitats during the winter, such as deltas, estuaries, tidal creeks and coastal lagoons.
