The golden-bellied starfrontlet (Coeligena bonapartei) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae.

Their upper back is shining dark green that transitions through greenish copper to the golden orange rump.

The female's forehead is plain green; the rest of the upperparts are colored like the male's but are duller.

[8] The golden-bellied starfrontlet is found in the Eastern Andes of Colombia between Boyacá Department and the Metropolitan Area of Bogotá.

[8] The golden-bellied starfrontlet gathers nectar from tubular flowers, usually at low to medium heights.

In addition to feeding on nectar it captures small arthropods by gleaning from foliage, hovering, and by hawking.

[8] The golden-bellied starfrontlet's breeding season is not known in detail but appears to span from January to possibly July.
