The Balyan family (Western Armenian: Պալեաններ; Turkish: Balyan ailesi or Palyan ailesi) was a prominent Armenian family of Ottoman court architects in the service of Ottoman sultans and members of the Ottoman dynasty during the 18th and 19th centuries. For five generations, they designed and constructed numerous major buildings in the Ottoman Empire, including palaces, mansions, konaks, kiosks, yalis, mosques, churches, and various public buildings, mostly in Constantinople (present-day Istanbul). The nine well-known members of the family served six sultans in the course of almost a century and played an important role in the Westernization of Ottoman architecture during the Tanzimat period.
