Kabile (Bulgarian: Кабиле) or Cabyle is a village in southeastern Bulgaria, part of the Tundzha municipality, Yambol Province.

The ancient Thracian city of Kabile was one of the most important and largest towns in Thrace and its architectural remains are impressive, many of them preserved and restored.

Zaychi vrah, the last hill of the Sredna Gora mountain range, can be found 1.5 km north of Kabile.

From discovered inscriptions, the cohort II Lucensium, from Abritus and consisting of nominally 480 foot soldiers and 120 cavalry, was stationed in the fort from 136 (under Hadrian) to 192 AD and built the associated thermae in 166 to 169.

The large and elaborate tribunorum for about 12 officers and dating from the early 270s was excavated in 2017 and a recently translated inscription shows another larger cohort (milliaria) with about 800 foot soldiers was present.

[9] New large public buildings were built and Kabyle became one of the most important cities of Thracia following the reforms of Emperor Diocletian.

[11] The Hellenistic city had defensive walls from the last quarter of the 4th century BC, an agora and temples to Jupiter Dolichenus, the Thracian Horseman, Asclepius and Hygia.

The military fort occupied part of the city from Roman times, including the later barracks (one for cavalry) and large thermal baths.

Smaller thermal baths lie inside the civilian town dating initially from the early 1st century BC and were at first associated with a palaestra.
