The oystercatchers are a group of waders forming the family Haematopodidae, which has a single genus, Haematopus.
They are found on coasts worldwide apart from the polar regions and some tropical regions of Africa and South East Asia.
The exceptions to this are the Eurasian oystercatcher, the South Island oystercatcher, and the Magellanic oystercatcher, which also breed inland, far inland in some cases.
In the past there has been a great deal of confusion as to the species limits, with discrete populations of all black oystercatchers being afforded specific status but pied oystercatchers being considered one single species.

The name oystercatcher was coined by Mark Catesby in 1731 as a common name for the North American species H. palliatus, described as eating oysters.
Yarrell in 1843 established this as the preferred term, replacing the older name sea pie or sea-pie.
The genus name Haematopus comes from the Greek haima αἳμα blood, pous πούς foot.
