Karaite Judaism or Karaism is a Jewish religious movement characterized by the recognition of the written Tanakh alone as its supreme authority in halakha and theology. Karaites believe that all of the divine commandments which were handed down to Moses by God were recorded in the written Torah without any additional Oral Law or explanation. Unlike mainstream Rabbinic Judaism, which regards the Oral Torah, codified in the Talmud and subsequent works, as authoritative interpretations of the Torah, Karaite Jews do not treat the written collections of the oral tradition in the Midrash or the Talmud as binding.

Jewish religious movements, sometimes called "denominations", include diverse groups within Judaism which have developed among Jews from ancient times. Today in the west, the most prominent divisions are between traditionalist Orthodox movements and modernist movements such as Reform Judaism originating in late 18th century Europe, Conservative originating in 19th century Europe, and other smaller ones, including the Reconstructionst and Renewal movements which emerged later in the 20th century in the United States.
