A military statement said the aircraft was shot down after it ignored three warnings for it to leave.
It was not clear which country the drone belonged to. It crashed inside Turkey's borders.
Turkey earlier this month complained about violation of its airspace by Russian warplanes. The intrusions also drew strong condemnation from its NATO allies.
Igor Konashenkov, spokesman for the Russian defense ministry, told Russian news agencies Friday that all Russian jets have safely returned to their base and all Russian drones "are functioning normally."
