The Hungarian-Turkish Friendship Park is a public park in Csertő, southwestern Hungary, dedicated in memorial to the Battle of Szigetvár fought in 1566 between the Ottoman Empire and the Hungarian and Croatian defenders of the Szigetvár Castle. The park was established in 1994 and opened jointly by Hungarian and Turkish officials.

The siege of Szigetvár or the Battle of Szigeth was a siege of the fortress of Szigetvár, Kingdom of Hungary, that blocked Sultan Suleiman's line of advance towards Vienna in 1566. The battle was fought between the defending forces of the Habsburg monarchy under the leadership of Nikola IV Zrinski, former Ban of Croatia, and the invading Ottoman army under the nominal command of Sultan Suleiman the Magnificent.
