Kiliia or Kilia (Ukrainian: Кілія, IPA: [ki.lʲiˈjɑ]; Russian: Килия; Romanian: Chilia Nouă) is a city in Izmail Raion, Odesa Oblast, southwestern Ukraine.

The Chilia branch of the Danube river, which separates Ukraine from Romania, is named after it.

[3] The city was founded by Stephen the Great of Moldavia, in order to counteract the Ottoman Empire which had taken control over Chilia Veche in the 15th century.

[4] Kiliia was taken by the Russian army under the command of the general Ivan Gudovich during Russo-Turkish War (1787–1792).

The Times of London reported that "35,000 of the inhabitants were involved in a general massacre," an incident that had "been celebrated in prose and poetry."

After being bombarded by the Anglo-French fleet in July 1854 during the Crimean War, it was given to Romania in the Treaty of Paris (1856).
