《非战公约》，全称《关于废弃战争作为国家政策工具的普遍公约》，亦称《巴黎非战公约》（Pact of Paris）或《凯洛格—白里安公约》（Kellogg-Briand Pact），是1928年8月27日在巴黎签署一项国际公约，该公约规定放弃以战争作为国家政策的手段和只能以和平方法解决国际争端或冲突，由于该公约本身是创建在理想主义的国际关系理论下，所以该公约没有发挥实际作用，但是该项公约是人类第一次放弃战争做为国家的外交政策。

该公约由法国外交部长白里安、美国国务卿凯洛格于1927年发起，目的是法美联手抑制德国的力量。最初的签字国有15个，分别是法国、美国、英国、德国、意大利、比利时、波兰、捷克、日本、印度。1929年7月24日公约正式生效，至1934年5月签字国共达64个。

The Kellogg–Briand Pact (or Pact of Paris, officially General Treaty for Renunciation of War as an Instrument of National Policy) is a 1928 international agreement in which signatory states promised not to use war to resolve "disputes or conflicts of whatever nature or of whatever origin they may be, which may arise among them." Parties failing to abide by this promise "should be denied of the benefits furnished by this treaty." It was signed by Germany, France and the United States on August 27, 1928, and by most other nations soon after. Sponsored by France and the U.S., the Pact renounces the use of war and calls for the peaceful settlement of disputes. Similar provisions were incorporated into the Charter of the United Nations and other treaties and it became a stepping-stone to a more activist American policy. It is named after its authors, United States Secretary of State Frank B. Kellogg and French foreign minister Aristide Briand.
