Gori Fortress is a medieval citadel located in the city of Gori, Georgia, standing atop a rocky hill overlooking the city. Archaeological evidence indicates the area had been fortified since at least the last centuries BCE, but the fortress first appears in written records from the 13th century. Its strategic location along important trade routes meant that controlling Gori Fortress was critical for maintaining political and military control over the Shida Kartli region of Georgia. As a result, it was continually fought over and captured by Georgians, Ottomans, Persians, and Russians over the centuries

The fortress underwent major renovations and rebuilding numerous times, most significantly in the 17th century under King Rostom and in the late 18th century under King Erekle II, giving it much of its current structural form. Key surviving structures today include the western-facing Tskhra-kara ("Nine Gates") walls and a small church in the southeast section. However, the fortress suffered major damage in a 1920 earthquake and remains largely in ruins.

Visitors can access the fortress by a short walk up the hill from Gori city center. Despite its dilapidated state, it offers impressive views of Gori and is an interesting glimpse into Georgia's medieval military history for travellers.
