Offences Against the Person Act (with its variations) is a stock short title used for legislation in the United Kingdom, in the Republic of Ireland, and in Hong Kong relating to offences against the person. It seems to have been derived from the long title of the Act which has come to be known as the Offences against the Person Act 1828. It is sometimes abbreviated to OAPA, as in "OAPA 1861".
