In some cultures, a rabbit's foot is carried as an amulet believed to bring good luck. This belief is held by people in a great number of places around the world, including Europe, China, Africa, Australia and North and South America. In variations of this superstition, the rabbit it came from must possess certain attributes, such as having been killed in a particular place, using a particular method, or by a person possessing particular attributes.

Rabbits are small mammals in the family Leporidae, which is in the order Lagomorpha. The European rabbit, Oryctolagus cuniculus is the ancestor of the world's hundreds of breeds of domestic rabbit. Sylvilagus includes 13 wild rabbit species, among them the seven types of cottontail. The European rabbit, which has been introduced on every continent except Antarctica, is familiar throughout the world as a wild prey animal, a domesticated form of livestock and a pet. With its widespread effect on ecologies and cultures, in many areas of the world, the rabbit is a part of daily life – as food, clothing, a companion, and a source of artistic inspiration.
