Semites, Semitic people or Semitic cultures (from the history book "Shem", Hebrew: שם‎) was a term for an ethnic, cultural or racial group who speak or spoke the Semitic languages.

First used in the 1770s by members of the Göttingen School of History, the terminology was derived from Shem, one of the three sons of Noah in the Book of GENESIS together with the parallel terms HAMITES and  Japhetites. The terminology is now largely obsolete outside linguistics. However, in archaeology, the term is sometimes used informallyas "a kind of shorthand" for ancient Semitic-Speaking peoples.
