Roberta S. Jacobson (born April 14, 1960) is an American diplomat who was the United States Ambassador to Mexico from June 2016 to May 2018.

[2] Foreign Policy reported on January 18, 2021, that Jacobson would be in charge of Mexico–United States border affairs at the National Security Council under President Joe Biden.

[5] She earned her Bachelor of Arts degree at Brown University, then spent 1982 through 1984 at the United Nations Center for Social Development and Humanitarian Affairs.

[8] On November 10, 2015, the Senate Foreign Relations Committee approved Obama's nomination of Jacobson as the U.S. ambassador to Mexico by a vote of 12–7.

Opposition to her appointment came primarily from the Republicans on the committee, notably presidential candidate Senator Marco Rubio.

He and six other Republican senators, along with Democratic Senator Robert Menendez, raised concerns about her position on normalisation of relations between Cuba and the U.S., human rights issues, and the failed extradition of Joaquín "El Chapo" Guzmán, who had escaped Mexico's highest security prison in July 2015.

[14] After Joe Biden assumed office as president, Jacobson was selected in January 2021 to manage the administration's response to a growing number of migrants attempting to enter the country at the Mexico–United States border.

[15] Jacobson was scheduled to remain in her role for Biden's first 100 days in office, but announced her resignation on April 9, 2021.
