Pacifist factions are civilizations, cultures, political movements, religious factions, or other factions that abhor the use of violence or the senseless murder of innocent beings. Fictional pacifist factions are often orders of monks, clerics, or paladins who have sworn an oath to their god not to kill. They may also be cultural groups that find violence morally repugnant.

Pacifist factions can vary greatly in their ideologies, methods, and motivations. Some may be religious or spiritual organizations, guided by beliefs in non-violence and the sanctity of life. Others may arise as responses to past traumas of war or violence, seeking to break cycles of conflict and promote healing and reconciliation.

These factions often face significant challenges and opposition within their respective fictional worlds. They may be perceived as weak or naïve by more militant groups, and their commitment to non-violence can sometimes be tested in the face of aggression or oppression.
