Interfaith marriage in Judaism

Interfaith marriage in Judaism (also called mixed marriage or intermarriage) was historically looked upon with very strong disfavor by Jewish leaders, and it remains a controversial issue among them today. Many Jews followed the Talmud and all of resulting Jewish law Halakha until the advent of new Jewish movements following the Jewish Enlightenment resulted in the "Haskala"; in Halakha marriage between a Jew and a gentile is both prohibited, and also void under Jewish law.

A 2020 survey conducted in the United States by the Pew Research Center found that 42% of all currently married Jewish respondents indicated they have a non-Jewish spouse. Among those who had married since 2010, 61% were intermarried and the percent increases to 72% when Orthodox Jews were excluded from the data.
