This is a list of bioterrorist incidents.

It has been suggested that Bioterrorism#Incidents be merged into this article. (Discuss) Proposed since March 2024.

The definitions of bioterrorism for the purpose of this article are:

• The use of violence or of the threat of violence in the pursuit of political, religious, ideological or social objectives
• Acts committed by non-state actors (or by undercover personnel serving on the behalf of their respective governments)
• Acts reaching more than the immediate target victims and also directed at targets consisting of a larger spectrum of society
• Both mala prohibita (i.e., crime that is made illegal by legislation) and mala in se (i.e., crime that is inherently immoral or wrong)
• Committed with the use of biological agents

The following criteria of violence or threat of violence fall outside of the definition of this article:

• Wartime (including a declared war) or peacetime acts of violence committed by a nation state against another nation state regardless of legality or illegality and are carried out by properly uniformed forces or legal combatants of such nation states (See biological warfare)
• Reasonable acts of self-defense, such as the use of force to kill, apprehend, or punish criminals who pose a threat to the lives of humans or property
• Legitimate targets in war, such as enemy combatants and strategic infrastructure that form an integral part of the enemy's war effort such as defense industries and ports
• Collateral damage, including the infliction of incidental damage to non-combatant targets during an attack on or attempting to attack legitimate targets in war
• Targeted murders or poisonings carried out with the use of biological agents, not for political or religious purposes
• Plans that were not carried out
