Interfaith Marriage

Interfaith marriage, traditionally called mixed marriage, is marriage (either religious or civil) between partners professing different religions.

Interfaith marriage typically connotes a marriage in which both partners remain adherents to their distinct religion, and as such it is distinct from concepts of religious conversion, religious assimilation, cultural assimilation, religious disaffiliation, and apostasy. Nevertheless, despite the distinction, these issues typically are associated with many aspects of interfaith marriage.

Some religious doctrines prohibit interfaith marriage. Others traditionally oppose interfaith marriage but may allow it in limited circumstances. Several major religions have left the matter relatively unspecified and still others allow it entirely but with some requirements for ceremony and custom.

An ethno-religious group's resistance to interfaith marriage can constitute a form of self-segregation.
