部队防护状态（英语：Force Protection Condition，简称FPCON）是美国一个监督海外恐怖威胁的衡量系统，由美国国防部制定，其等级由美国北方司令部设置。此系统共分为五级，当中以DELTA为最高，NORMAL为最低。不同级别均明确指出军事设施需要采取的防护措施。与戒备状态不同，部队防护状态所保护的目标是军事设施，而非戒备状态的平民。美国国防部在更改部队防护状态的级别时，必须考虑到恐怖袭击对军事设施可能造成的威胁、可动员的保安部队数量、以及美国与世界各国之间的关系。

部队防护状态前称「威胁状态」（THREATCON），但美国国防部于2001年6月将系统改为现名，因为旧名很容易让人将此系统与美国国务院的威胁评估系统（System of threat assessment）混淆。

In United States security, Force Protection Condition (FPCON for short) is a terrorist threat system overseen by the Department of Defense directive, and describes the amount of measures needed to be taken by security agencies in response to various levels of terrorist threats against military facilities, as opposed to DEFCON, which assesses the amount of military forces needed to be deployed in a situation with a certain likelihood of attack against the civilian population. The decision on what level of FPCON to implement is affected by the current threat of terrorism towards military facilities and personnel, the amount of security forces available, and current relationships between the United States and the world, which may affect the chances of an attack. FPCON was previously known as THREATCON, until it was renamed in June 2001 due to confusion with United States State Department system of threat assessment.
