Numenius is a bird genus commonly known as curlews which are characterised by their long, slender, downcurved bills and mottled brown plumage.
The English name may have been influenced by the Old French corliu, "messenger", from courir , "to run".

The genus name Numenius is from Ancient Greek noumenios, a bird mentioned by Hesychius. It is associated with the curlews because it appears to be derived from neos, "new" and mene "moon", referring to the crescent-shaped bill.
