Samurlu is a village in the Alexandropol uezd of the former Iravan governorate, later in the former Gizil Goch (Gukasyan) district, and currently in the Shirak province. The provincial centre lies 38 km to the northeast of the town of Gumru, at a height of 1,970 m above sea level.

The village was initially inhabited by Azerbaijanis. According to the Treaty of Adrianople (1829), after the settlement of Armenians in the territory of the Iravan khanate, the Azerbaijani population of the village moved to Türkiye. Armenians were settled there from the Turkish province of Erzurum in 1828–1829.

The toponym was coined by adding the identifying suffix “-lu” to the Old Turkic ethnonym “Samur” which means “the place of the Samur tribe”. It is an ethnotoponym.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 12 November 1946, the village was renamed “Sarapat”. According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was integrated into the administrative area of the Shirak province.
