The velvet-purple coronet (Boissonneaua jardini) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae.

Males have a velvety black head with a glittering purplish blue crown; the rest of the upperparts are shining bluish green.

[5] The velvet-purple coronet is found along the Pacific slope of the Andes from southwestern Colombia's Chocó Department to northwestern Ecuador's Pichincha Province.

It mostly inhabits the interior and edges of wet mossy primary and secondary forest, but also occurs in shrubby landscapes.

[5] The IUCN has assessed the velvet-purple coronet as being of Least Concern, though it has a somewhat restricted range and its population size is not known and thought to be decreasing.
