"Misinformation shared on social media has a serious impact," Kardashian West wrote in a statement on Tuesday.
The move is part of the #StopHateforProfit campaign which was organised by civil rights activists.
The celebrities will freeze their accounts for 24 hours on Wednesday.
"I can't sit by and stay silent while these platforms continue to allow the spreading of hate, propaganda and misinformation - created by groups to sow division and split America apart," Kardashian West said.
"Misinformation shared on social media has a serious impact on our elections and undermines our democracy," she added.
