Estrilda is a genus of estrildid finch in the family Estrildidae.

Most of the genus is found in Africa with one species, the Arabian waxbill, ranging into Asia.

Some species are kept as pets and have been accidentally introduced to various parts of the world.

The genus Estrilda was introduced in 1827 by the English naturalist William Swainson with the common waxbill as the type species.

[1] The name of the genus is from astrild, the specific epithet of the common waxbill that was introduced by Carl Linnaeus in 1758.
