Amirdovlat Amasiatsi (Armenian: Ամիրդովլաթ Ամասիացի; c. 1420-1496), also called Amirdovlat of Amasia, was a 15th-century Armenian physician and writer. He wrote several works on medicine and science, some aimed at professional audiences and some at ordinary people. All his works were written in Middle Armenian, making them accessible to ordinary readers and not just to scholars. Amirdovlat was born in Amasia around 1420. He travelled extensively. He wrote the majority of his works in Constantinople, where he was chief physician to Mehmed II. He died in Amasia or Bursa on December 8, 1496.
