Concealing a birth is the act of a parent (or other responsible person) failing to report the birth of a child. The term is sometimes used to refer to hiding the birth of a child from friends or family, but is most often used when the appropriate authorities have not been informed about a stillbirth or the death of a newborn. This is a crime in many countries, with varying punishments.

England and Wales, and Northern Ireland
In England and Wales, and in Northern Ireland, section 60 of the Offences against the Person Act 1861 creates the offence of concealing the birth of a child:
If any woman shall be delivered of a child, every person who shall, by any secret disposition of the dead body of the said child, whether such child died before, at, or after its birth, endeavour to conceal the birth thereof, shall be guilty of a misdemeanor, and being convicted thereof shall be liable, at the discretion of the court, to be imprisoned for any term not exceeding two years, ...
The proviso to this section, as extended by any subsequent enactment, was repealed for England and Wales by section 10 of, and paragraph 13(1)(a) of Schedule 2 to, and Part III of Schedule 3 to, the Criminal Law Act 1967. Originally, the proviso allowed the jury to find an alternative verdict of this offence on a charge of murder. In England and Wales, it was subsequently extended to allow the jury to find an alternative verdict of this offence on a charge of child destruction or a charge of infanticide.
Section 60 of the Offences against the Person Act 1861 is framed on section 14 of the Offences against the Person Act 1828 (which applied to England, including Wales and Berwick) and section 17 of the 10 Geo 4 c 34, which applied to Ireland. This offence was previously created by section 4 of the Lord Ellenborough's Act (43 Geo 3 c 58) (1803). This in turn replaced "An Act to prevent the Murthering of Bastard Children" (21 Jac 1 c 27) (1623) and another Act applying to Ireland, which were repealed by section 3.
The words "if any woman shall be delivered of a child, every person" were retained in section 60 after a division in the select committee of the House of Commons, and the members were equally divided upon the subject. The word "secret" was in like manner retained after a division in the committee.
Section 31 of the Offences against the Person Act 1828 made provision in relation to any person who should counsel, aid or abet the commission of, amongst other things, a misdemeanour under section 14.
Concealment of birth of newly born child
113. (1) Any person who, without a lawful burial order, disposes of the body of any newly born child with intent to conceal the fact of its birth, whether the child died before, during or after birth, shall be guilty of an offence and liable on conviction to a fine or to imprisonment for a period not exceeding three years. (2) A person may be convicted under subsection (1) although it has not been proved that the child in question died before its body was disposed of.
In the United States, concealing birth was once a crime punishable by capital punishment. In 1785, Hannah Piggen from Massachusetts was the last person to be put to death for concealing the birth/death of an infant.
