Marcela Giammattei

Ana Marcela Dinorah Giammattei Cáceres (born 8 August 1992) is a Guatemalan attorney and politician. Giammattei is daughter of former President of Guatemala Alejandro Giammattei and his wife Rossana Cáceres.

As her parents are separated, she accompanied her father to his inauguration on 14 January 2020 holding the Bible and Constitution, being her only appearance at an official event during her father's presidency.

In 2024, she was sanctioned along with her father and brothers by the United States Department of State. Giammattei worked at the Central American Bank for Economic Integration, but was fired in 2024, as a result of the sanctions against her.
