Old Tbilisi refers to the historical parts of Tbilisi. Although the term "Old Tbilisi" has long been used to denote the oldest part of the city, it was only in 2007 that it became an official administrative distinct, while also incorporating several historical neighbourhoods formerly included in the districts of Mtatsminda-Krtsanisi, Isani-Samgori, and Didube-Chugureti. The official district was abolished in 2013, with its territories allotted to several other divisions of the capital; however, locals and visitors continue to refer to historical districts as "Old Tbilisi" without precise boundaries.
