Musluglu was a village in the Aghbaba area (nahiya) of the Kars uezd of the former Kars province, later in the former Amasiya (Aghbaba) district, and present-day Shirak province. It was located 17 km to the northwest of the settlement of Amasiya. According to Armenian sources, the village was inhabited by the Garapapags.

The village was inhabited by 150 Azerbaijanis in 1886, 199 in 1897, 223 in 1908 and 317 Azerbaijanis in 1914. The village was within the Provisional National Government of the Southwestern Caucasus founded in Kars in 1918–1919. The village was destroyed as a result of Armenian attacks in February 1920. After the establishment of Soviet power in present-day Armenia, the village was integrated to the Alexandropol uezd within the Aghbaba area in 1921 by the Treaty of Kars and a part of the inhabitants returned to the village. The village was inhabited by 57 Azerbaijanis in 1922 and 82 Azerbaijanis in 1926.

The toponym was coined by adding the suffix “-lu” to the word “musluk” meaning “a tap” in Turkish. The village was abolished in the 1930s. At present, it lies in ruins.
