Chynadiiovo or Chynadiieve (Ukrainian: Чинадійово, Чинадієвe; Rusyn: Чинадійово; Hungarian: Szentmiklós; Russian: Чинадиев; Slovak: Činadno) is a rural settlement in Mukachevo Raion, Zakarpattia Oblast, Ukraine.

Péter Perényi, who owned Szentmiklós in the early 15th century, commenced building a castle.

After the defeat of Rákóczi's War for Independence Emperor Charles VI gave Mukachevo and Chynadiiovo to Archbishop Lothar Franz von Schönborn.

A year later it passed to his nephew, Bishop Friedrich Karl von Schönborn-Buchheim.

On this day, a new law entered into force which abolished this status, and Chynadiiovo became a rural settlement.
