Gelochelidon is a genus of terns. It was considered a monotypic genus until the Australian tern was split from the gull-billed tern.
Taxonomy

The genus Gelochelidon was introduced in 1830 by the German zoologist Alfred Brehm.[2] The type species is the gull-billed tern.[3] The name combines the Ancient Greek gelaō meaning "to laugh" with khelidōn meaning "swallow".[4]

The genus contains 2 species:[5]
