Mari Carmen Aponte (born 1946) is an American attorney and diplomat who served as the United States Ambassador to Panama in the Biden administration from 2022 to 2025. She previously served as acting assistant secretary of state for Western Hemisphere affairs on May 5, 2016. She also served as U.S. ambassador to El Salvador from August 2010 until December 2011 and again from June 14, 2012, until December 2015. Before that she was serving as a member of the board of directors of Oriental Group, a major financial and banking services enterprise in Puerto Rico. President Obama also nominated her as the United States' permanent representative to the Organization of American States, but the Senate had not acted upon that nomination upon adjournment in December 2014.
