The Siege of Tkvarcheli refers to the eventually unsuccessful siege of the Abkhazian town of Tkvarcheli during the 1992–93 War in Abkhazia by the National Guard of Georgia. The siege lasted from October 1992 to September 1993, covering almost the entire duration of the war. It was accompanied by inconclusive fighting in surrounding villages. Russian aid, both humanitarian and military, was critical for the defence of the town which suffered a severe humanitarian crisis during the siege.
