In the Hebrew Bible and Jewish religious law, a mamzer (, , "estranged person"; plural mamzerim) is a person who is born as the result of certain forbidden relationships or incest (as it is defined by the Bible), or the descendant of such a person. Mamzer status () is not synonymous with the traditional western definition of illegitimacy, since it does not include children whose mothers were unmarried when they were born. Definition Etymology Some have explained the word mamzer as the masculine noun form derived from the root m-z-r, having a meaning of spoilt/corrupt. According to Strong's Concordance: "from an unused root meaning 'to alienate'; a mongrel, i. e., born of a Jewish father and a heathen mother". The Talmud explains the term homiletically as consisting of the words mum (defect) and zar (strange/alien), a euphemism for an illicit union in the person's lineage.

According to the Mishnah, a mamzer is the offspring of a biblically forbidden union for which his progenitors are liable to extirpation at the hands of heaven. An exception to this rule is when a Jewish man cohabits with a menstruant woman: Although he is liable thereby to extirpation, the child born from such union is not a mamzer. The practical bearing of this ruling is that it excludes from such defamation a child born outside of wedlock, and which child is often wrongly called "bastard" under common law. According to the Shulchan Aruch, a new line of mamzerim can only be produced by two Jews but the product of a non-Jew and a mamzeret (female mamzer) is a mamzer. There are two categories of mamzerim.
