Yeni Mosque, Komotini, Ottoman mosque in Komotini, Greece.

The Yeni Mosque in Komotini is a prayer building with a square hall, single dome, and minaret that combines Ottoman structural forms with Greek neoclassical elements. The interior displays a clear spatial organization typical of Ottoman religious architecture from this period.

The mosque's founding is attributed to Ekmekçizade Ahmed Pasha, defterdar (chief finance minister) under Sultan Ahmed I and Osman II. The muftiate dates it to 1585, though the founder's name suggests shortly after 1600. His külliye included a medrese, a double hammam and a mektep. The current form dates from 1902, and the building was refurbished in 2007–2008.

The name Yeni Camii means "New Mosque" in Turkish, yet it predates the Old Mosque of 1608. It serves the large Muslim community of Komotini, called Gümülcine in Turkish, and remains in active use for worship.

The mosque is in the centre of Komotini, next to the Muftiate of Rhodope and adjoining the Clock Tower; the ruins of the Ahmed Pasha hammam lie east of it on Ifaistou Square. It is an active place of Muslim worship serving the city's Muslim community, so visits should be timed outside prayer times and the prayer hall entered respectfully.

The building preserves the only surviving Iznik tiles from the 1580s in Greece. These ceramics represent the highest quality of Ottoman tile craftsmanship and stand as remarkably rare examples of this art form.
