The Bar-winged Rail (Nesoclopeus poecilopterus) was a species of bird in the Rallidae family. It was endemic to Fiji and was last collected ca 1890 in Viti Levu. The species was idenitifed from twelve 19th century specimens, some of which are known to be in Boston, London and New York. The last unconfirmed sighting of this bird was in 1973.

It was a flightless island ground-nesting forest/freshwater swamp dweller and is believed to have disappeared after the introduction of the mongoose and cats to the islands.
