The retaliatory move from the Trump Administration comes weeks after Russia forced a cut in US diplomatic staff in Moscow by hundreds.
"The US has fully implemented the decision by the Government of the Russian Federation to reduce the size of our mission in Russia. We believe this action was unwarranted and detrimental to the overall relationship between our countries," State Department Spokesperson Heather Nauert said.
With this action both countries will remain with three consulates each, she added.
Last month, Russia forced the cut in US diplomatic staff earlier this year in retaliation for American sanctions. The US had to reduce its diplomatic staff by 755 people.

Moscow ordered the US to cut its diplomatic and technical staff in Russia by more than half to 455 people, after Congress overwhelmingly approved new sanctions against Russia.
Secretary of State Rex Tillerson had said the US would respond by September.
"While there will continue to be a disparity in the number of diplomatic and consular annexes, we have chosen to allow the Russian Government to maintain some of its annexes in an effort to arrest the downward spiral in our relationship," Nauert said.
"The United States hopes that, having moved toward the Russian Federation's desire for parity, we can avoid further retaliatory actions by both sides and move forward to achieve the stated goal of both of our presidents: improved relations between our two countries and increased cooperation on areas of mutual concern," she said.
