The 2020 United States Mixed Doubles Curling Championship was held from February 27 to March 1 at the Bemidji Curling Club in Bemidji, Minnesota. The twelve teams were divided into two pools of six teams each. Each pool played a full round robin with the top three from each pool proceeding to the playoffs. The winning team of Tabitha Peterson and Joe Polo was supposed to represent the United States at the 2020 World Mixed Doubles Curling Championship in Kelowna, Canada but the event got cancelled due to the COVID-19 pandemic. They will instead compete at the 2021 World Mixed Doubles Curling Championship in Aberdeen, Scotland as the 2021 U.S. Mixed Doubles National Championship was postponed due to the pandemic.
