A hoof ( or ), plural hooves ( or ) or hoofs , is the tip of a toe of an ungulate mammal, strengthened by a thick, horny, keratin covering. The hoof consists of a hard or rubbery sole and a hard wall formed by a thick nail rolled around the tip of the toe. The weight of the animal is normally borne by both the sole and the edge of the hoof wall. Hooves grow continuously, and are constantly worn down by use.

Hands off our Forest (HOOF) is a campaign group formed in 2010 to fight the UK Government's proposed sale of publicly owned land in the Forest of Dean. 'Hands off our Forest' describe themselves as a broad alliance of groups and individuals.
