	In [[computer programming]], a '''control variable''' is a [[program variable]] that is used to regulate the [[flow of control]] of the program.

	In definite iteration, control variables are variables which are successively assigned (or bound to) values from a predetermined sequence.<ref name="Watt">{{cite book \|last1=Watt \|first1=David A. \|title=Programming Language Design Concepts \|url=https://archive.org/details/programminglangu00watt_497 \|url-access=limited \|date=2004 \|publisher=Wiley \|pages=[https://archive.org/details/programminglangu00watt_497/page/n102 84]-85}}</ref>

	In some programming languages, control variables are just ordinary variables used for manipulating the program flow.
