The Dome of the Rock (Arabic: قبة الصخرة, romanized: Qubbat aṣ-Ṣakhra) is an Islamic shrine located on the Temple Mount in the Old City of Jerusalem, a site also known to Muslims as the Haram al-Sharif or Al-Aqsa. Its initial construction was undertaken by the Umayyad Caliphate on the orders of Abd al-Malik during the Second Fitna in 691–692 CE, and it has since been situated on top of the site of the Second Jewish Temple (built in c. 516 BCE to replace the destroyed Solomon's Temple and rebuilt by Herod the Great), which was destroyed by the Romans in 70 CE. The original dome collapsed in 1015 and was rebuilt in 1022–23. The Dome of the Rock is the world's oldest surviving work of Islamic architecture.

Its architecture and mosaics were patterned after nearby Byzantine churches and palaces, although its outside appearance was significantly changed during the Ottoman period and again in the modern period, notably with the addition of the gold-plated roof, in 1959–61 and again in 1993. The octagonal plan of the structure may have been influenced by the Byzantine-era Church of the Seat of Mary (also known as Kathisma in Greek and al-Qadismu in Arabic), which was built between 451 and 458 on the road between Jerusalem and Bethlehem.

The Foundation Stone (or Noble Rock) that the temple was built over bears great significance in the Abrahamic religions as the place where God created the world as well as the first human, Adam. It is also believed to be the site where Abraham attempted to sacrifice his son, and as the place where God's divine presence is manifested more than in any other place, towards which Jews turn during prayer. The site's great significance for Muslims derives from traditions connecting it to the creation of the world and the belief that the Night Journey of Muhammad began from the rock at the centre of the structure.

Designated by UNESCO as a World Heritage Site, it has been called "Jerusalem's most recognizable landmark" along with two nearby Old City structures: the Western Wall and the "Resurrection Rotunda" in the Church of the Holy Sepulchre. It is the earliest archaeologically attested religious structure to be built by a Muslim ruler and the building's inscriptions contain the earliest epigraphic proclamations of Islam and of the Islamic prophet Muhammad; the inscriptions proved to be a milestone, as afterward they became a common feature in Islamic structures and almost always mention Muhammad. The Dome of the Rock remains a "unique monument of Islamic culture in almost all respects", including as a "work of art and as a cultural and pious document", according to historian Oleg Grabar.
