Pertev Mehmet Paşa Mosque, also known as Yeni Cuma Cami meaning "New Friday Mosque" in Turkish, is a 16th-century Ottoman mosque in the town of Izmit, Turkey.[1][2][3] The architect was Mimar Sinan. It was built for Pertev Mehmed Paşa, an Ottoman vizier during the reigns of sultan Suleyman I and Selim II. The construction was finished in 1579.[2][4] The mosque is part of a larger complex (Külliye) which originally included a madrasa, hammam, caravanserai, fountain and a lower education school.[2] The mosque itself is a single domed structure and the dome has 24 windows.
