The social policies of eugenics in Nazi Germany were composed of various ideas about genetics. The racial ideology of Nazism placed the biological improvement of the German people by selective breeding of "Nordic" or "Aryan" traits at its center. These policies were used to justify the involuntary sterilization and mass-murder of those deemed "undesirable".

Eugenics is a set of beliefs and practices that aim to improve the genetic quality of a human population. Historically, eugenicists have attempted to alter human gene pools by excluding people and groups judged to be inferior or promoting those judged to be superior. In recent years, the term has seen a revival in bioethical discussions on the usage of new technologies such as CRISPR and genetic screening, with heated debate around whether these technologies should be considered eugenics or not.
