The swamp rabbit, also called the cane-cutter, is a large cottontail rabbit found in the swamps and wetlands of the southern United States. The species has a strong preference for wet areas, and it will take to the water and swim.

Cottontail rabbits are in the Sylvilagus genus, which is in the Leporidae family. They are found in the Americas. Most Sylvilagus species have stub tails with white undersides that show when they retreat, giving them their characteristic name. However, this feature is not present in all Sylvilagus, nor is it unique to the genus.
