The Ten Commandments, or Decalogue, are a list of religious and moral imperatives that, according to Judeo-Christian tradition, were authored by God and given to Moses on the mountain referred to as "Mount Sinai" (Exodus 19:23) or "Horeb" (Deuteronomy 5:2) in the form of two stone tablets. They feature prominently in Judaism and Christianity.

In Biblical Hebrew, the commandments are called עשרת הדברים (translit. Aseret ha-Dvarîm) and in Rabbinical Hebrew עשרת הדברות (translit. Aseret ha-Dibrot), both translatable as "the ten terms." The English name "Decalogue" is derived from the Greek translation δεκάλογος dekalogos "ten terms", found in the Septuagint at Exodus 34:28 and Deuteronomy 10:4.

The phrase "Ten Commandments" is generally used to refer to similar passages in Exodus 20:2–17 and Deuteronomy 5:6–21. Some scholars distinguish between this "Ethical Decalogue" and a different series of ten commandments in Exodus 34:11–27 that they call the "Ritual Decalogue". Although Exodus 34 contains ten imperative statements, the passages in Exodus 20 and Deuteronomy 5 contain fourteen or fifteen. However, the Bible assigns the count of ten to both lists. Various denominations divide these statements into ten in different ways, and may also translate the Commandments differently.
