Devin (Bulgarian: Девин [ˈdɛvin]) is a spa town in Smolyan Province in the far south of Bulgaria.

The town itself is located in the vicinity of the popular ski resort of Pamporovo which is 35 km east of Devin.

The waters have been claimed to treat and heal a variety of maladies: conditions of the skeletal, peripheral nervous, cardiovascular and pulmonary systems, skin disorders and others.

The situation of Devin offers access to nearby gorges, rock formations, caves, forests, natural reserves with protected and endemic species, and most of all, clean air.

"Kastraklii", "Kazanite" and "Shabanitza" are natural reserves in the region around Devin with centuries-old pine and spruce forests and protected plant and animal communities.

Dairy cattle rearing, fish farming, mushroom picking and cultivation, potato growing and others are of significance to the local economy.

Between 1878 and 1886, Devin formed a part of the short-lived and unrecognised Republic of Tamrash, an entity created by the local Pomaks who rejected the creation of Eastern Rumelia (to which it would have belonged).
