Signagi or Sighnaghi is a town in Georgia's easternmost region of Kakheti and the administrative center of the Signagi Municipality. Although it is one of Georgia's smallest towns, Signagi serves as a popular tourist destination due to its location at the heart of Georgia's wine-growing regions, as well as its picturesque landscapes, pastel houses and narrow, cobblestone streets. Located on a steep hill, Signagi overlooks the vast Alazani Valley, with the Caucasus Mountains visible at a distance.

Kakheti is a region (mkhare) formed in the 1990s in eastern Georgia from the historical province of Kakheti and the small, mountainous province of Tusheti. Telavi is its administrative center. The region comprises eight administrative districts: Telavi, Gurjaani, Qvareli, Sagarejo, Dedoplistsqaro, Signagi, Lagodekhi and Akhmeta.
