The Jews (Hebrew: יְהוּדִים‎, Yehudim), also known as the Jewish people, are an ethnoreligious group originating in the Israelites or Hebrews of the Ancient Near East. The Jewish ethnicity, nationality, and religion are strongly interrelated, as Judaism is the traditional faith of the Jewish nation.^[3][4][5] Converts to Judaism, whose status as Jews within the Jewish ethnos is equal to those born into it, have been absorbed into the Jewish people throughout the millennia.

Secular Jewish culture embraces several related phenomena; above all, it is the culture of secular communities of Jewish people, but it can also include the cultural contributions of individuals who identify as secular Jews, or even those of religious Jews working in cultural areas not generally considered to be connected to religion.

The word secular in secular Jewish culture, therefore, refers not to the type of Jew but rather to the type of culture. For example, religiously observant Jews who write literature and music or produce films with non-religious themes are participating in secular Jewish culture, even if they are not secular themselves.

The Jewish people is generally considered to be an ethnoreligious community rather than solely a religious grouping; Judaism guides its adherents in both practice and belief, so that it has been called not only a religion, but also a "way of life". This makes it difficult to draw a clear distinction between the cultural production of members of the Jewish people, and culture that is specifically Jewish. Furthermore, not all individuals or all cultural phenomena can be easily classified as either "secular" or "religious", a distinction native to European Enlightenment thinking and foreign to most of the history of non-European Jews.

Throughout history, in eras and places as diverse as the ancient Hellenic world, in Europe before and after the Age of Enlightenment, in Islamic Spain and Portugal, in North Africa and the Middle East, in India and China, and in the contemporary United States and Israel, Jewish communities have seen the development of cultural phenomena that are in some sense characteristically Jewish without being at all specifically religious. Some factors in this come from within Judaism, others from the interaction of Jews with others around them, and others from the inner social and cultural dynamics of the community, as opposed to religion itself. This phenomenon has led to considerably different Jewish cultures unique to their own communities, each as authentically Jewish as the next.
