The Cinderella waxbill (Glaucestrilda thomensis) is a near-threatened species of estrildid finch found in drier regions of south-western Angola around the Namibe Province, north and east to the south-west of the Huíla Province and north to Fazenda do Cuito in Huambo - also in the extreme north-western part of Namibia. It has an estimated global distribution of 95,700 km² (36,900 sq mi).

The Cinderella waxbill is found in subtropical and tropical (lowland), dry shrubland, savannah and forest habitats at altitudes of 200 to 500 m (660 to 1,640 ft). It is observed that the recent development of a hydroelectric plant on the Cunene River at Epupa Falls has caused changes to insect biodiversity which were relied on by the Cinderella waxbill during feeding of its young - thus threatening its food source to be depleted.

The waxbill also eats grass seeds, nectar and insects. The Cinderella is diurnal.
