The garden emerald (Chlorostilbon assimilis) is a small hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Costa Rica and Panama. The garden emerald was at one time considered a subspecies of the blue-tailed emerald (Chlorostilbon mellisugus). As its own species, it is monotypic.
The garden emerald is 7.8 to 8.5 cm (3.1 to 3.3 in) long and weighs about 3 to 4.1 g (0.11 to 0.14 oz). The adult male has dark metallic green upperparts with bluish green uppertail coverts. Its forked tail is blue-black and the central feathers have a light bluish green gloss. Its underparts are a brighter metallic green than the upperparts, sometimes with a light blue sheen, and it has white thigh tufts. The adult female has bright metallic green to bronze green upperparts with bluish green uppertail coverts. Its tail is blue-black, with dull metallic green central feathers and pale gray tips on the outer ones. It has dusky cheeks, a white or grayish white spot behind the eye, and pale gray underparts. Juvenile males are like the adult female but darker gray below.
