The Amidah, also called the Shemoneh Esreh, is the central prayer of the Jewish liturgy. Observant Jews recite the Amidah at each of three daily prayer services in a typical weekday: morning (Shacharit), afternoon (Mincha), and evening (Ma'ariv). On Shabbat, Rosh Chodesh, and Jewish festivals, a fourth Amidah (Mussaf) is recited after the morning Torah reading, and once per year, a fifth Amidah (Ne'ilah) is recited, around sunset, on Yom Kippur. Due to the importance of the Amidah, in rabbinic literature, it is simply called "hatefila". According to legend, the prayer was composed by the rabbis of the Anshei Knesset HaGedolah. Accordingly, in Judaism, to recite the Amidah is a mitzvah de-rabbanan, i. e., a commandment of rabbinic origin.

Jewish prayer is the prayer recitation that forms part of the observance of Rabbinic Judaism. These prayers, often with instructions and commentary, are found in the Siddur, the traditional Jewish prayer book.
