Lonchura is a genus of the estrildid finch family, and includes munias (or minias) and mannikins. They are seedeating birds that are found in Africa and in South Asia from India, Bangladesh, Sri Lanka east to Indonesia, Papua New Guinea, and the Philippines. The name mannikin is from Middle Dutch mannekijn 'little man' (also the source of the different bird name manakin).
Some of the Lonchura species were formerly placed in Spermestes. Others have been placed in a genus of their own, Euodice.
