Yalta (Ukrainian and Russian: Я́лта) is a resort city on the south coast of the Crimean Peninsula in Ukraine surrounded by the Black Sea. It serves as the administrative center of Yalta Municipality, one of the regions within Crimea. Yalta, along with the rest of Crimea, is internationally recognised as part of Ukraine, and is considered part of the Autonomous Republic of Crimea. However, it is occupied by Russia, which annexed Crimea in 2014 and regards the town as part of the Republic of Crimea. According to the most recent census, its population was 76,746 (2014 Census).

The city is located on the site of the ancient Greek colony of Yalita. It is said to have been founded by the Greek settlers who were looking for a safe shore (Γιαλός, yalos in Greek) on which to land. It is situated on a deep bay facing south towards the Black Sea, surrounded by the mountain range Ai-Petri. It has a warm humid subtropical climate and is surrounded by numerous vineyards and orchards.

The area became famous when the city held the Yalta Conference as part of the Allied World War II conferences in 1945.

The term "Greater Yalta" is used to designate a part of the Crimean southern coast spanning from Foros in the west to Gurzuf in the east and including the city of Yalta and multiple adjacent urban settlements.
