护身符（英语：Amulet）是在民间信仰中，指能够带给拥有者好运，或是保护拥有者，让他避免恶运及鬼神侵害的任何物体。不同人类族群中，根据其本身的文化，有不同的护身符信仰。例如西洋的幸运兔脚，幸运钱币与十字架，中国道教的符箓，都是一种护身符。

An amulet is an object whose most important characteristic is the power ascribed to it to protect its owner from danger or harm. Amulets are different from talismans as a talisman is believed to bring luck or some other benefit, though it can offer protection as well. Amulets are often confused with pendants—charms that hang from necklaces—any given pendant may indeed be an amulet, but so may any other charm which purports to protect its owner from danger.
