Direction finding (DF) refers to the establishment of the direction from which a received signal was transmitted. This can refer to radio or other forms of wireless communication. By combining the direction information from two or more suitably spaced receivers (or a single mobile receiver), the source of a transmission may be located in space viatriangulation.

A configuration on a map that acts as a direction finder is known as a compass rose. A compass rose is also known as a windrose.
