Anti-Terrorist Hoax and False Report Act of 2001 - Amends the Federal criminal code to set penalties for knowingly and maliciously imparting, conveying, or communicating false or fraudulent information concerning the existence of activity which would constitute a violation of prohibitions regarding biological weapons, chemical weapons, nuclear materials, or weapons of mass destruction under circumstances in which such information may reasonably be believed and is reasonably likely to cause any response by a Federal, State, or local government agency.

Directs the court to order: (1) restitution to all victims of such an offense, including for any losses suffered as a proximate result; and (2) the defendant to reimburse all Federal, State, and local government entities for any expenses incurred in response to protect public health or safety.
