The Java sparrow (Lonchura oryzivora), also known as Java finch, Java rice sparrow or Java rice bird, is a small passerine bird. This estrildid finch is a resident breeding bird in Java, Bali and Bawean in Indonesia. It is a popular cage bird, and has been introduced in a large number of other countries. Some taxonomists place this and the Timor sparrow in their own genus Padda.
