Pirin peak, Mountain summit in Pirin National Park, Bulgaria.

Pirin peak is a mountain summit at 2,593 meters in the Pirin mountain range of southwestern Bulgaria. It forms part of the protected Baiuvi Dupki Reserve and features alpine vegetation and expansive views across the surrounding terrain.

The summit was long known as Golyama Dzhindzhiritsa and was renamed Pirin in 1942. It lies in the Bayuvi Dupki–Dzhindzhiritsa Reserve of Pirin National Park, in Simitli Municipality, about 14 km west of Kresna. The granite peak's northeast wall later became an alpine climbing site with several routes.

The peak was called Golyama Dzhindzhiriza until 1942, when it received the name of the whole mountain range. Its present name is shared with the massif, while the old one survives in the name of the Bayuvi Dupki–Dzhindzhiriza reserve that surrounds the summit. Visitors who reach the top sign a notebook kept in a container there.

The peak lies off the main hiking routes and is rarely climbed. The usual starting points are the village of Brezhani, the Predel hut (about 5 hours) and the Moravitsa hut (5 to 6 hours), with Yavorov hut about 4 hours away. The summit holds a container with a visitor logbook.

The peak's old name, Golyama Dzhindzhiritsa, was used until 1942. It is the northernmost of the range's large summits and lies within the Bayuvi Dupki–Dzhindzhiritsa Reserve. A container holding a visitor logbook sits on the rarely climbed top.
