Stillbirth: The birth of a dead baby, the delivery of a fetus that has died before birth for which there is no possibility of resuscitation. The distinction between a stillbirth and a miscarriage is arbitrary. The dividing line has variously set at 20 to 24 weeks of gestation or at a specific weight, such as 500g. Before that time it is a miscarriage, and after that time it is a stillbirth.
