Urochroa is a genus of hummingbird containing two recently-split species.

The genus Urochroa was introduced in 1856 by the English ornithologist John Gould to accommodate the rufous-gaped hillstar which is thus the type species.

[1][2] The genus name combines the Ancient Greek oura meaning "tail" with khroa meaning "colour" or "complexion".

[3] The green-backed hillstar was formerly considered to be a subspecies of the rufous-gaped hillstar.
