The Homeland Security Presidential Directive (HSPD) 5 was an executive order issued on the 28th of February, 2003 by President George W. Bush.

The main purpose of the HSDP 5 was to provide guidance to the Department of Homeland Security (DHS) and enhance the ability to manage domestic incidents in the United States of America.
