综摄（英语：syncretism，又称融合主义）指的是调和或统合信念（如宗教上）的冲突，也可指对于调和或统合所做的努力，例如宗教混合的客观过程。两个以上的宗教在接触与和解后，发展出彼此文化特质的交流现象，借由宗教教义的交互体现，达到多元活动内容与丰富的融合现象。

英语的「综摄」（Syncretism）一词最早出现在1618年的牛津字典，但事实上在西元的前宗教进化过程中，就已出现多起。例如古希腊。之后的基督教、天主教、伊斯兰教，东亚的儒教、佛教、道教（三教）与民间信仰，甚至现代新兴宗教，综摄现象均成为宗教发展中无可避免的过程。

Syncretism (/ˈsɪŋkrətɪzəm/) is the combining of different, often contradictory beliefs, while blending practices of various schools of thought. Syncretism involves the merger and analogizing of several originally discrete traditions, especially in the theology and mythology of religion, thus asserting an underlying unity and allowing for an inclusive approach to other faiths. Syncretism also occurs commonly in expressions of arts and culture (known as eclecticism) as well as politics (syncretic politics).
