The settlement which was built in connection with production of molybdenum in 1939, got its name from the river which flows near the village. And  the name of the Paragachay River is related with the name of the "Parağa" (Paragha) village and means "river which flows through the Paragha village". According to some researchers, the name of the Parağa village made from the components of the Turkic word of "para" (village) and Persian word of "gah" (location) meaning "the place of the village" or "the place on the other bank". In the dialect of the Nakhchivan of the Azerbaijani language, the word "parağa" means "foothill of the mountain", "slope of the mountain", and this is related with the geographical location of the settlement.
