A '''local variable''' (also called '''automatic storage''', etc) in a [[programming language]] is one that only has storage allocated for it when the [[subroutine|procedure]] in which the variable is defined is entered, during the execution of the [[program]]. Once that particular invocation of the procedure is exited, the values of all the automatic variables in it disappear.

Automatic variables are usually implemented with a [[stack]].
