Nakhchivan Eyalet was possibly an eyalet of the Ottoman Empire. Nakhchivan (Nahçivan) was recorded as a beylerbeylik in 1603. [1] In 1591, there were references to a beylerbeylik of Erivan and Nakhchivan, and scholar Donald E. Pitcher speculates that Nakhchivan may have never been a separate eyalet. [1]
