Omega (majuscule: Ω, minuscule: ω; Greek Ωμέγα) is the 24th and last letter of the Greek alphabet. In the Greek numeric system, it has a value of 800. The word literally means "great O" (ō mega, mega meaning 'great'), as opposed to omicron, which means "little O" (o mikron, micron meaning "little").[1] This name is Byzantine; in Classical Greek, the letter was called ō (), whereas the omicron was called ou (οὖ).[2] The form of the uppercase letter derives from that of an omicron (Ο) broken up at the side (Greek Omega 09.svg), with the edges subsequently turned outwards (Greek Omega 05.svg, Greek Omega 03.svg, Greek Omega 07.svg).[3] The modern lowercase shape goes back to the uncial form Greek uncial Omega.svg, a form that developed during the 3rd century BC in ancient handwriting on papyrus, from a flattened-out form of the letter (Greek Omega 08.svg) that had its edges curved even further upwards.[4]

Phonetically, the Ancient Greek Ω is a long open-mid o [ɔː], equal to the vowel of British English raw. In Modern Greek Ω represents the same sound as omicron. The letter omega is transcribed ō or simply o.

Omega (the last letter of the Greek alphabet) is often used to denote the last, the end, or the ultimate limit of a set, in contrast to alpha, the first letter of the Greek alphabet. In the New Testament book of Revelation, God is declared to be the "alpha and omega, the beginning and the end, the first and the last".[5]

Omega was also adopted into the early Cyrillic alphabet. See Cyrillic omega (Ѡ, ѡ). A Raetic variant is conjectured to be at the origin or parallel evolution of the Elder Futhark ᛟ.
