The Presidential Emergency Operations Center (PEOC, PEE-ock) is a bunker underneath the East Wing of the White House.

The first White House bunker was built during World War II to protect President Franklin D. Roosevelt in the event of an aerial attack on the national capital of Washington, D.C.

During a breach of White House security, including violations of the Washington, D.C. Air Defense Identification Zone (P-56 airspace), the president and other protectees are relocated to the executive briefing room, next to the PEOC.

These included Vice President Dick Cheney, First Lady Laura Bush, Lynne Cheney, Condoleezza Rice, Mary Matalin, "Scooter" Libby, Joshua Bolten, Karen Hughes, Stephen Hadley, David Addington, Secret Service agents, U.S. Army major Mike Fenzel serving on a White House Fellowship, and other staff including Norman Mineta.
