This is a list of former mosques in Greece. It lists former mosques (, , ) and places of worship for Muslims in Greece. It lists some, but by no means all, of the old historical mosques of Greece. The term former mosque in this list includes any Muslim mosque (building) or site used for Islamic prayer (Salah) in Greece, but is no longer.

Mosques have existed within the modern Greece borders since the era of the Emirate of Crete (824–961). But no mosques of the Emirate remain as they were torn down and remaining Muslims were either killed, enslaved or converted to Christianity after the Byzantine reconquest of Crete (961).Canard (1971), pp. 1084–1085Kazhdan (1991), p. 96 Therefore, currently the oldest mosque in Greece and the entire Balkan peninsula is believed to be the Çelebi Sultan Mehmed Mosque, the first in Didymoteicho (Western Thrace), built between 1389 and 1402.

Most of the listed former mosques date from the late 14th century to the early 20th century, when various parts of modern Greece were at some point a part of the Ottoman Empire. Beyond the new mosques built during the Ottoman period, several Christian churches throughout Greece were also converted to mosques over time upon conquest, like the church of Hagios Demetrios in Thessalonica. Those were gradually converted to churches following Greece's independence and annexation of other regions.

Many Ottoman mosques and other Muslim monuments, especially in southern Greece, were either destroyed during the Greek War of Independence in the 1820s and successive wars and conflicts. During periods of nationalist uprising and wars against the Ottoman and later the Turkish army, the newly independent Greek nation showed little respect for the monuments of a faith identified with the enemy. Several Ottoman mosques were confiscated and repurposed for use as churches, government offices, and other civilian purposes.

Many more mosques in Greece were closed or abandoned due to the 1923 Population exchange between Greece and Turkey; as a result, 355,000 to 400,000 Muslims left Greece, most of them forcibly made to leave their lands, livelihoods, and mosques.

Many former mosques and other religious buildings also survived in the provinces of Macedonia, Thrace, Crete, and the Dodecanese Island, which were integrated into the Greek State in the early 20th century. By then, there was already a law to protect religious buildings of all faiths.

The surviving former mosques or other religious structures are nowadays protected as monuments. Many of them are still used as government buildings and churches, while many others have been restored and used as museums, exhibition, concert centers and tourist attractions.
