Brown Babies is a term used for children born to black soldiers and white women during and after the Second World War. Other names include "war babies" and "occupation babies." In Germany they were known as Mischlingskinder, a term first used under the Nazi regime for children of mixed Jewish-German parentage. As of 1955, African-American soldiers had fathered about 5,000 children in the American Zone of Occupied Germany. In Occupied Austria, estimates of children born to Austrian women and Allied soldiers ranged between 8,000 and 30,000, perhaps 500 of them biracial. In the United Kingdom, West Indian members of the British military, as well as African-American soldiers in the US Army, fathered 2,000 children during and after the war. A much smaller and unknown number, probably in the low hundreds, was born in the Netherlands, but the lives of some have been followed into their old age and it is possible to have a better understanding of the experience that would unfold for all of the Brown Babies of World War II Europe.

War children are those born to a local parent and a parent belonging to a foreign military force. Having a child by a member of a belligerent force, throughout history and across cultures, is often considered a grave betrayal of social values. Commonly, the native parent is disowned by family, friends, and society at large. The term "war child" is most commonly used for children born during World War II and its aftermath, particularly in relation to children born to fathers in German occupying forces in northern Europe. In Norway, there were also Lebensborn children. The discrimination suffered by the local parent and child in the postwar period did not take into account widespread rapes by occupying forces, or the relationships women had to form in order to survive the war years.
