The white-bellied thicket fantail (Rhipidura leucothorax) is a species of bird in the family Rhipiduridae.

Juveniles are similar to adults, but browner in color, with spots on the breast and totally black bill.

This species is also similar to Sooty thicket fantail (R. threnothorax) but that one has no white tip of the tale.

It is built of dried reeds or smth like that, lined with roots bound with spiders' webs.

The nests are placed in the branch forks at a height of about 0.5 m. The clutch consists of 2 eggs 16-19 * 13-14.5 mm in size.
