Black Hebrew Israelite's (also called Black Hebrews, African Hebrew Israelite's, and Hebrew Israelite's) are groups of Black Americans who believe that they are descendants of the ancient Israelite's. Black Hebrews adhere in varying degrees to the religious beliefs and practices of both Christianity and Judaism. They are not recognized as Jews by the greater Jewish community. Many choose to identify themselves as Hebrew Israelite's or Black Hebrews rather than Jews in order to indicate their claimed historic connections. Books linking the ancestry of Jews and Blacks have become popular such as "From Babylon to Timbuktu: A History of the Ancient Black Races Including the Black Hebrews."

Many Black Hebrew groups were founded in the United States during the late 19th and early 20th centuries, from Kansas to New York, by both African Americans and West Indian immigrants. In the mid-1980s, the number of Black Hebrews in the United States was between 25,000 and 40,000. In the 1990s, the Alliance of Black Jews (which is no longer operating) estimated that there were 200,000 African-American Jews; this estimate was based on a 1990 survey conducted by the Council of Jewish Federations.
