The greenish puffleg (Haplophaedia aureliae) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae. It is found in Colombia, Ecuador, Panama, and Peru. The greenish puffleg is 9 to 11.6 cm (3.5 to 4.6 in) long and weighs 4 to 6.5 g (0.14 to 0.23 oz). Males of the nominate subspecies have green upperparts with a coppery hue on the head and neck. The underparts are duller green with a grayish white scaly appearance. The leg puffs are white on the outside and buff on the inside. The slightly forked tail is blue-black. Females are similar but their underparts are more heavily scaled and their leg puffs entirely white. Juveniles resemble females. Subspecies H. a. caucensis has grass green upperparts with a more intense coppery tinge on the head and rump than the nominate, and also a white patch on the belly. Males of H. a. floccus are similar to caucensis but with paler green underparts and less of a coppery tinge on the upperparts, but in addition bright cinnamon uppertail coverts. The female's foreneck and breast have prominent white scaling. Males of H. a. galindoi are darker green above and below compared to floccus and the scaling of females' underparts is more muted. H. a. russata has a longer bill and brighter copper upperparts than the nominate and its underparts are scaled brown rather than grayish white. H. a. cutucuensis is like the nominate but with much heavier grayish white scaling on the underparts.
