Shahbulag Castle (Azerbaijani: Şahbulaq qalası, literally "Spring of the Shah") is an 18th-century fortress near Aghdam in Azerbaijan built by the Karabakh Khan Panah Ali.

[9] Panah Ali Khan relocated everyone from Bayat Castle to Shahbulag, which brought him within close proximity of the highlands ruled by the five Armenian melikdoms.

[10][9] Following the construction of Panahabad fortress in Shusha, Panah Ali Khan relocated the notables, dignitaries, and tribal leaders there.

[1] Today, Shahbulag Castle remains an important historic and cultural remnant of the Karabakh Khanate period.

When the castle was under Armenian control, a small museum was operated there, storing artifacts found during excavations at the adjacent archaeological site of Tigranakert.

[16] The castle and the Aghdam District were returned to Azerbaijan on 20 November 2020 per the ceasefire agreement that ended the 2020 Nagorno-Karabakh war.
