Jeleč (Serbian Cyrillic: Јелеч) is a medieval fortification located in southwestern Serbia, 12 km south of present-day Novi Pazar, on one of the three peaks of Rogozna mountain.

The area between Raška and Ibar, where the Rogozna mountain forms a natural border towards the Pannonian Basin, was the heart of the Serbian medieval state during the early reign of the Nemanjić dynasty, the Grand Principality of Serbia.

When the aspirations of the Nemanjić to expand south came to fruition, starting with the reign of Milutin, the fortification saw its military value decrease due to being deep in inner Serbia and isolated on a mountain peak.

During the fracturing of the Serbian Empire, it was first under the realm of Vojislav Vojinović, then his nephew Nikola Altomanović, and finally the house of Branković.

With the Ottoman expansion into Serbia, many of the local population were converted to Islam and the nearby settlements were abandoned or reduced to very small villages with single houses.
