开源宗教(英语:Open-source religion)是一种利用开放源代码方法来创造宗教信仰的尝试。为此，该宗教系统得通过其信徒之间的互动来创造并且完善其理念。开源宗教的第一个例子是1990年代的"Yoism"。他们是一群自称是"Yoans"的团体，约有100人左右，成员除了来自世界各地外，主要来自于麻州的波士顿地区。这群人相信一个信仰体系应该是创建在自己启蒙的价值观和理念。

Open-source religions employ open-source methods for the sharing, construction, and adaptation of religious belief systems, content, and practice. In comparison to religions utilizing proprietary, authoritarian, hierarchical, and change-resistant structures, open-source religions emphasize sharing in a cultural Commons, participation, self-determination, decentralization, and evolution. They apply principles used in organizing communities developing open-source software for organizing group efforts innovating with human culture. New open-source religions may develop their rituals, praxes, or systems of beliefs through a continuous process of refinement and dialogue among participating practitioners. Organizers and participants often see themselves as part of a more generalized open-source and free-culture movement.
