Olga María del Carmen Sánchez Cordero Dávila is a Mexican politician and former jurist. She was the Secretary of the Interior of Mexico, and the first woman to ever hold this position. She previously served as an Associate Justice on the Supreme Court of Justice of the Nation, Mexico's highest federal court, from 26 January 1995 to 30 November 2015. She currently serves as a Senator and was President of the Senate of the Republic from 2021 to 2022.

The Mexican Secretariat for Home Affairs is the public department concerned with the country's domestic affairs, the presenting of the president's bills to Congress, their publication on the Official Journal of the Federation, and certain issues of national security. The country's principal intelligence agency, CISEN, is directly answerable to the Secretary of the Interior. The Secretary is a member of the President's Cabinet and is, given the constitutional implications of the post, the most important Cabinet Member. Additionally, in case of absolute absence of the President, the Secretary of Interior assumes the executive powers of the President provisionally. The Office is practically equivalent to Ministries of the Interior in most other countries and is occasionally translated to English as Ministry, Secretariat or Department of the Interior.
