布克农教（Bokononism），是美国文坛巨擘库尔特·冯内古特于其作品《猫的摇篮》中虚构的宗教。

布克农为书中的一个角色，是本教的创始者，原名李奥鲍伊强森。在一次船难中他登上圣罗伦佐岛，这是书中一个位于加勒比海的虚构岛屿，强森这个名字由岛上的方言发音后成为布克农。这个岛上的居民因环境限制生活十分困苦，布克农因此希望借由创建一个宗教，让岛上居民的心灵能脱离现实的贫困，变得快乐。

布克农教教义写在布克农之书内，布克农在布克农之书的第一页就写下了警语，告知这个宗教的一切都是谎言。信仰布克农教的人可以借由两个人的脚和脚相印，来进行与对方的交互及感知，这种仪式被称为布克-玛路。

Bokononism (/ˈboʊkoʊnɒnˌɪzəm/) is a fictitious religion invented by Kurt Vonnegut and practiced by many of the characters in his novel Cat's Cradle. Many of the sacred texts of Bokononism were written in the form of calypsos.

Bokononism is based on the concept of foma, which are defined as harmless untruths. A foundation of Bokononism is that the religion, including its texts, is formed entirely of lies; however, one who believes and adheres to these lies will have peace of mind, and perhaps live a good life. The primary tenet of Bokononism is to "Live by the foma that make you brave and kind and healthy and happy."
