The green broadbill (Calyptomena viridis) also known as the lesser green broadbill is a small bird in the family Calyptomenidae.

The bird is about 17 cm long, plumaged in brilliant green with a black ear patch, widely gaped bill, rounded head, short tail and three black bars on each wing. The beak itself is very weak and almost hidden by the crest above it. Both sexes are similar. The female is duller and has no black markings on its ear patch and wing coverts.
