Walking is one of the main gaits of terrestrial locomotion among legged animals. Walking is typically slower than running and other gaits. Walking is defined by an "inverted pendulum" gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the usable number of limbs—even arthropods, with six, eight, or more limbs, walk. In humans, walking has health benefits including improved mental health and reduced risk of cardiovascular disease and death.

चलना या चालन या टहलना भूमि पर जानवरों का गमन या संचलन का मुख्य प्रकार है और यह दौड़ने और रेंगने से अलग होता है।
