Burhinidae is a bird family which is often known as stone-curlews, or dikkops or thick-knees.
The family contains three genera: Hesperoburhinus, Burhinus and Esacus. The name Burhinus combines the Ancient Greek bous meaning "ox" and rhis, rhinos meaning "nose" (or "bill").

The stone-curlews are not closely related to the curlews, genus Numenius, that belong to the sandpiper family Scolopacidae.

Burhinus is a genus of birds in the family Burhinidae. The genus name Burhinus comes from the Greek bous for ox, and rhis for nose.
