The United States secretary of homeland security is the head of the United States Department of Homeland Security, the federal department tasked with ensuring public safety in the United States. The secretary is a member of the Cabinet of the United States. The position was created by the Homeland Security Act following the Terrorist attacks of September 11, 2001.

The new department consisted primarily of components transferred from other Cabinet departments because of their role in homeland security, such as the Coast Guard, the Federal Protective Service, U.S. Customs and Border Protection (which includes the United States Border Patrol), U.S. Immigration and Customs Enforcement (which includes Homeland Security Investigations), the United States Secret Service and the Federal Emergency Management Agency.

The current secretary of homeland security is Kristi Noem, since January 25, 2025.
