In human anatomical terms, the leg is the part of the lower limb that lies between the knee and the ankle, and the term "lower limb" is used to describe the colloquial leg. This article generally follows the common usage.

The leg from the knee to the ankle is called the cnemis (nee'mis) or crus. The calf is the back portion and the shin is the front.

Legs are often used metaphorically in many cultures to indicate either strength or mobility. The supporting columns of an object may be referred to as legs as well, as in chair legs.

Function and cultural aspects

Adolescent and adult females in many Western cultures often remove the hair from their legs. Toned, tanned, shaved legs are sometimes perceived as a sign of youthfulness and are often considered attractive in these cultures.
