飞行面条怪物（英语：Flying Spaghetti Monster，缩写：FSM，又译飞面大神，简称面神），是讽刺性的虚构宗教飞行面条怪物信仰（Church of the Flying Spaghetti Monster，或称Pastafarianism，又译飞天面条神教、飞行面条神教、飞面神教）信奉的神祇，此虚构宗教的讽刺对象主要是某些宗教教派所宣称的智能设计论（生物并非出于演化，而是源自某种超自然智能的设计）并把其加入美国公立学校的自然科学课。该教声称“飞行面条怪物”创造了世间万物，因而尊奉其为上帝。据信徒所言，飞天面条神教是一个「真实及合法程度不亚于其他宗教的宗教」。该教在波兰和荷兰被法律承认为正式宗教；在新西兰，飞天面条神教则已获授权，可以举办婚礼，并在2016年4月举办首场具法律认受性的飞面神教式婚宴，同时美国联邦法官约翰·M·杰拉德裁定“飞天面条神教”并不是真正的宗教。

The Flying Spaghetti Monster (FSM) is the deity of the Church of the Flying Spaghetti Monster or Pastafarianism (a portmanteau of pasta and Rastafarian), a social movement that promotes a light-hearted view of religion and opposes the teaching of intelligent design and creationism in public schools. According to adherents, Pastafarianism is a "real, legitimate religion, as much as any other." Pastafarianism is legally recognized as a religion in Poland, in The Netherlands, and in New Zealand – where Pastafarian representatives have been authorized to celebrate weddings and where the first legally recognized Pastafarian wedding was performed in April 2016. In the same month in the United States, a Federal Judge ruled that the "Church of the Flying Spaghetti Monster" is not a real religion.
