The Lazarev Institute of Oriental Languages, (Armenian: Լազարևի արևելյան լեզուների ինստիտուտ, romanized: Lazarevi arevelyan lezuneri institut) established in 1815, was a school specializing in orientalism, with a particular focus on that of Armenia, and was the principal cultural center of the Armenian diaspora in Moscow, Russia.

The former institute, located on Armyansky Lane, is listed as a memorial building and currently houses the Embassy of Armenia (Armenian: Ռուսաստանում Հայաստանի դեսպանություն, romanized: Rrusastanum Hayastani despanut’yun) to Russia.

In 1872 it was formally divided into two sections, one of which continued as a gymnasium, while the other presented a three-year course in the Armenian, Persian, Arabic, Turkish, and Georgian languages, history, and culture.

Between 1758 and 1812 the main house was gradually expanded, notably by Ovakim Lazarev, son of Lazar and founder of the institute.

Subsequent restorations retained the street facades, but removed Grigoriev's finishes on the side wall, revealing 17th-century brickwork.
