Estrildidae, or estrildid finches, is a family of small seed-eating passerine birds of the Old World tropics and Australasia. 
They comprise species commonly known as munias, mannikins, firefinches, parrotfinches and waxbills. 

The word Estrildidae is derived from the Greek word "estrildis," meaning "sparrow-like," and the Latin suffix "-idae," denoting a family of animals.
