Qoph or Qop (Phoenician Qōp ) is the nineteenth letter of the Semitic abjads. Aramaic Qop is derived from the Phoenician letter, and derivations from Aramaic include Hebrew Qof ק, Syriac Qōp̄ ܩ and Arabic Qāf ق.
The origin of the glyph shape of qōp () is uncertain. It is usually suggested to have originally depicted either a sewing needle, specifically the eye of a needle (the Hebrew קוף means "hole"), or the back of a head and neck (qāf in Arabic meant "nape"). According to an older suggestion, it may also have been a picture of a monkey and its tail.
The Arabic letter ق is named قاف qāf. It is written is several ways depending in its position in the word:
|Position in word:||Isolated||Final||Medial||Initial|
It is usually transliterated into Latin script as q, though some scholarly works use ḳ.
According to Sibawayh, author of the first book on Arabic grammar, the letter is pronounced as a voiced phoneme. As noted above, Modern Standard Arabic has the voiceless uvular plosive /q/ as its standard pronunciation of the letter, but dialectical pronunciations vary as follows:
- [q]: In Druze dialects, most of the variants of Maghrebi, Northern Mesopotamian Arabic, a number of Yemeni accents, and partially in Gulf Arabic.
- [ɡ]: In Hejazi Arabic, Najdi Arabic, Gulf Arabic, Libyan Arabic, rural Jordan, Southern Mesopotamian Arabic and some forms of Yemeni and Sa'idi Arabic (of Southern Egypt) and partially in Maghrebi dialects.
- [d͡z]: In Najdi Arabic 
- [ʔ]: In Egyptian Arabic, as well as Levantine Arabic and forms of Algerian Arabic and Moroccan Arabic from around Tlemcen and Fes respectively.
- [ɢ]: In Sudanese Arabic and some forms of Yemeni Arabic.
- [k]: In rural Palestinian Arabic it is often pronounced as a voiceless velar plosive [k].
- [d͡ʒ]: Optionally in Iraqi and in Gulf Arabic, it is sometimes pronounced as a voiced postalveolar affricate [d͡ʒ].
Note, however, that most dialects of Arabic do use the sound [q] for this letter when it is found in learned words borrowed from standard Arabic into the respective dialect.

The earliest Arabic manuscripts show qāf in several variants: pointed (above or below) or unpointed. Then the prevalent convention was having a point above for qāf and a point below for fāʼ; this practice is now only preserved in manuscripts from the Maghribi, with the exception of Libya and Algeria, where the Mashriqi form (two dots above: ق) prevails.
The Oxford Hebrew-English Dictionary transliterates the letter Qoph (קוֹף) a transliteration as q or k; and, when word-final, it may be transliterated as ck. The English spellings of Biblical names (as derived from Latin via Biblical Greek) containing this letter may represent it as c or k, e.g. Cain for Hebrew Qayin, or Kenan for Qenan (Genesis 4:1, 5:9).

Qof in gematria represents the number 100. Sarah is described in Genesis Rabba as בת ק' כבת כ' שנה לחטא, literally "At Qof years of age, she was like Kaph years of age in sin", meaning that when she was 100 years old, she was as sinless as when she was 20.

- Isaac Taylor, History of the Alphabet: Semitic Alphabets, Part 1, 2003: "The old explanation, which has again been revived by Halévy, is that it denotes an 'ape,' the character Q being taken to represent an ape with its tail hanging down. It may also be referred to a Talmudic root which would signify an 'aperture' of some kind, as the 'eye of a needle,' ... Lenormant adopts the more usual explanation that the word means a 'knot'.
- Qop may have been assigned the sound value /kʷʰ/ in early Greek; as this was allophonic with /pʰ/ in certain contexts and certain dialects, the letter qoppa continued as the letter phi. C.

- This variance has led to the confusion over the spelling of Libyan leader Muammar al-Gaddafi's name in Latin letters. In Western Arabic dialects the sound [q] is more preserved but can also be sometimes pronounced [ɡ] or as a simple [k] under Berber and French influence.
