"The deployment of Patriot missiles will achieve nothing but to provoke and, God forbid, result in being forced into an uncalculated action," Ali Akbar Salehi said in remarks reported by the official IRNA news agency.
"Their deployment will be more provocative rather than deterrent," he said and warning that the Patriot missiles would not "help regional security."
His comments came a day after Iran's top general issued a stern warning to Ankara over its planned hosting of the missile batteries, saying it was part of a Western plot to "create a world war."
