Yappa was a village in the territory of the Iravan uezd of the former Iravan governorate, later in the former Vedi (Ararat) district, and present-day Ararat province. The village was located in the Millidara region, between the Aghdagh and Gizilli Mountains and near the village of Chatma. The village was marked on the five-verst map of the Caucasus.

The village was inhabited by 62 Azerbaijanis in 1897, 55 in 1905 and 104 Azerbaijanis in 1914. The Azerbaijanis were attacked, massacred or expelled from the village by Armenian armed units in 1918. Only after the establishment of Soviet power in present-day Armenia, the Azerbaijanis managed to return to their village. The village was abolished in the 1930s. At present, it lies in ruins.

The toponym was coined on the basis of the name of the Turkic Yapma tribe.
