The Emirgan Park (Turkish: Emirgan Korusu or rarely Emirgan Parkı) is a historical urban park located in Emirgan neighborhood at the Bosphorus in Sarıyer district of Istanbul, Turkey. It is one of the largest public parks in Istanbul.

In the Byzantine era, the entire area, where today the park stretches, was covered with cypress trees and known as "Kyparades" or "Cypress Forest". It became known as "Feridun Bey Park", when the uninhabited land was granted in the mid-16th century to Nişancı Feridun Bey, a Lord Chancellor in rank in the Ottoman Empire.

In the 17th century, Ottoman sultan Murad IV (reigned 1623-1640) presented the estate to Emir Gûne Han, a Safavid Persian commander, who surrendered his sieged castle without any resistance, and followed him back to Istanbul. The name "Feridun Bey Park" was changed to "Emirgûne", which in time became corrupted to "Emirgan".

During the centuries, the estate's owner changed several times, and by the end of the 1860s, it was owned by Khedive Ismail Pasha (reigned 1863-1879), Ottoman governor of Egypt and Sudan. The area was used as the backyard of a large wooden yalı he built down at Bosporus. Further, he built within the park area three wooden pavilions, which still exists.
