The white-winged tern, or white-winged black tern (Chlidonias leucopterus or Chlidonias leucoptera), is a species of bird in the family Sternidae, the terns. It is a small species generally found in or near bodies of fresh water across much of the world, including Europe, Africa, Asia, and Australia. The genus name is from Ancient Greek khelidonios, "swallow-like", from khelidon, "swallow". The specific leptopterus is also Greek from leptos, "slender", and pteros, "feathered", itself from pteron, "wing".

The name 'white-winged tern' is the standard in most English-speaking countries; in the United Kingdom, this name is also the one used by the formal ornithological recording authorities, but the older alternative 'white-winged black tern' is still frequent in popular use.
