A posthumous birth is the birth of a child after the death of a parent.^[1] A person born in these circumstances is called a posthumous child or a posthumously born person. Most instances of posthumous birth involve the birth of a child after the death of its father, but the term is also applied to infants delivered shortly after the death of the mother, usually by caesarean section.^[2]

Posthumous birth has special implications in law, potentially affecting the child's citizenship and legal rights, inheritance, and order of succession. Legal systems generally include special provisions regarding inheritance by posthumous children and the legal status of such children. For example, Massachusetts law states that a posthumous child is treated as having been living at the death of the parent,^[3] meaning that the child receives the same share of the parent's estate as if the child had been born before the parent's death. Most states recognize a posthumous child born within a set time frame, normally 280 to 300 days after the death of the decedent father.^[4][5]

Another emerging legal issue in the United States is the control of genetic material after the death of the donor.^[6] United States law holds that posthumous children of U.S. citizens who are born outside the United States have the same rights to citizenship that they would have had if the deceased U.S. citizen parent had been alive at the time of their birth.^[7] In the field of assisted reproduction, snowflake children, i.e. those "adopted" as frozen embryos by people unrelated to them, can result in the birth of a child after the death of one or both of their genetic parents.

In the Middle Ages, it was traditional for posthumous children born in England to be given a matronymic surname instead of a patronymic one. This may in part explain why matronyms are more common in England than in other parts of Europe.^[10]

In Ancient Rome, posthumous children of noble birth were often given the cognomen (or third name) 'Postumus'. One example is Agrippa Postumus.

In Yoruba culture, posthumous children are given names that refer to the circumstances concerning the birth. Examples of this include Bàbárímisá, meaning that the Father saw (the child) and ran; Yeyérínsá, meaning that the mother saw (the child) and ran; Ikúdáyísí (or any name with the root dáyísí), which means that death spared the child; and Ẹnúyàmí, meaning that "I was surprised", referring to the fact that the tragic death of the father, mother, or both was sudden and surprising for the family.

The Bible's Old Testament mentions two named cases of posthumous children:

• Ashhur, youngest son of Hezron, born when his father had died when aged past 60 years. (1 Chronicles 2:21, 24)
• Ichabod, who was born when his mother, who subsequently died, heard news that his father Phinehas had been killed at the Battle of Aphek and paternal grandfather Eli accidentally killed afterwards. (1 Samuel 4:19–22)
