A Sefer Torah (Hebrew: ספר תורה‎; plural: ספרי תורה Sifrei Torah ; "Book(s) of Torah" or "Torah scroll(s)") is a handwritten copy of the Torah or Pentateuch, the holiest book within Judaism. It must meet extremely strict standards of production. The Torah scroll is mainly used in the ritual of Torah reading during Jewish services. At other times, it is stored in the holiest spot within a synagogue, the Aron Kodesh ("Holy Ark"), which is usually an ornate curtained-off cabinet or section of the synagogue built along the wall that most closely faces Jerusalem, the direction Jews face when praying.

The text of the Torah is also commonly printed and bound in book form for non-ritual functions. Then it is known as a Chumash ("five-part", for the five books of Moses), and is often accompanied by commentaries or translations.

Torah reading from a sefer Torah is traditionally reserved for Monday and Thursday mornings, as well as for Shabbat and Jewish holidays. The presence of a minyan is required for the reading of the Torah to be held in public during the course of the worship services. As the Torah is sung, following the often dense text is aided by a yad ("hand"), a metal or wooden hand-shaped pointer that protects the scrolls by avoiding unnecessary contact of the skin with the parchment.
