Flesh is the soft part of the body of a person or animal which is between the skin and the bones. In ordinary speech, it typically contrasts with bone, as in the merism flesh and bone. It mainly refers to skeletal muscle and associated fat, though it includes all other internal soft tissue. The softness of a human body is generally attributed to flesh, although muscles can also give a notion of hardness.

The word "meat" is normally used instead if animal flesh is intended as food.

In some instances, the term "flesh" will be used to describe the interior of fruits as well.
