Chrysuronia is a genus in the family of Hummingbirds, and consists of 9 species.

The blue-headed sapphire is a species of hummingbird in the family Trochilidae. It is found in Colombia and Ecuador. It formerly included the Humboldt's sapphire as a subspecies. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical mangrove forest, and heavily degraded former forest.

The golden-tailed sapphire is a species of hummingbird in the family Trochilidae. It is found in Bolivia, Brazil, Colombia, Ecuador, Peru, Trinidad and Tobago, and Venezuela.
Humboldt's sapphire is a species of hummingbird in the family Trochilidae. It is found in Colombia, Ecuador, and Panama. It was formerly considered a subspecies of the blue-headed sapphire. Its natural habitat is subtropical or tropical mangrove forest.

The plain-bellied emerald is a species of hummingbird in the family Trochilidae. It is found from north-eastern Venezuela, through the Guianas, to around São Luís in Brazil. Smaller disjunct populations are found in north-eastern Brazil as far south as Bahia. It occurs in a wide range of semi-open habitats, primarily in coastal regions. It is generally fairly common, and therefore considered to be of least concern by BirdLife International and consequently the IUCN.

The sapphire-throated hummingbird is a shiny metallic-green hummingbird found in Panama, Colombia, and more recently Costa Rica. The sapphire-throated hummingbird is separated into three subspecies; Chrysuronia coeruleogularis coeruleogularis, Chrysuronia coeruleogularis coelina, and Chrysuronia coeruleogularis conifis.

The shining-green hummingbird is a species of hummingbird in the family Trochilidae. It is found in Colombia and Venezuela. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical dry shrubland, and heavily degraded former forest.

The versicoloured emerald, sometimes placed in the genus Agyrtria, is a species of hummingbird from central and eastern South America.

The white-chested emerald is a hummingbird found in eastern Venezuela, the Guianas, Trinidad and far northern Brazil (Roraima). It has sometimes been placed in the genus Agyrtria, and the name A. chionopectus was formerly used for this species, as the name A. brevirostris was believed to be applicable to the versicolored emerald. While most current authorities maintain the view that A. brevirostris is the correct name for the white-chested emerald, it has recently been suggested that this is incorrect, in which case its scientific name would revert to A. chionopectus.
