Gagra is a city in Abkhazia, the breakaway republic of Georgia, sprawling for 5 km on the northeast coast of the Black Sea, at the foot of the Caucasus Mountains. Its subtropical climate made Gagra a popular health resort in Imperial Russian and Soviet times.
The town is still much frequented by Russian tourists, who come from the Russian resort of Sochi, situated just 22 km to the north.
 The chief landmarks of Gagra are:

• ruins of the Abaata fortress (4th-5th cent. AD);
• 6th-century church, said to be the oldest in Abkhazia;
• Marlinsky defensive tower (1841);
• 19th-century palace of the Prince of Oldenburg.
