Boar hunting is the practice of hunting wild boar, feral pigs, warthogs, and peccaries. Boar hunting was historically a dangerous exercise due to the tusked animal's ambush tactics as well as its thick hide and dense bones rendering them difficult to kill with premodern weapons.

A feral pig is a domestic pig which has gone feral, meaning it lives in the wild. The term feral pig has also been applied to wild boars, which can interbreed with domestic pigs. They are found mostly in the Americas and Australia. Razorback and wild hog are Americanisms applied to feral pigs or boar–pig hybrids.
