The Mosque of Pasha Qasim, also known as the Gazi Kasim Mosque, is a historic mosque located in the city of Pécs, Hungary. It was built in the 16th century during the Ottoman rule of Hungary, and is one of the few remaining examples of Ottoman architecture in the country.

The mosque was originally built as a church in the 13th century, but was converted into a mosque by the Ottomans in the mid-16th century. It was named after Pasha Gazi Kasim, who was a high-ranking Ottoman military commander and governor of the region at the time.

The mosque has a square plan with a central dome and four smaller domes, and features intricate tilework and calligraphy on the walls and ceilings. It also has a minaret, which is the only remaining minaret in Hungary.
