Christopher Thomas Landau (born November 13, 1963) is a Spanish-born American lawyer and diplomat who has served as the United States deputy secretary of state since 2025. He previously served as the United States ambassador to Mexico from 2019 to 2021.

Landau studied law at Harvard University. After graduation, he clerked for several justices of the Supreme Court, before whom he subsequently argued multiple cases. After being confirmed as United States ambassador to Mexico, he was sworn in by a justice he clerked for.

In December 2024, President-elect Trump nominated Landau to serve as the United States deputy secretary of state in his second administration.
