The Ranger Tab is a military decoration of the United States Army which signifies completion of the U.S. Army Ranger School, a three month course providing instruction in small-unit combat tactics in woodland, mountain, and swamp operations.

Those graduating from Ranger School are presented with the Ranger Tab which is worn on the upper left sleeve of a military uniform. The tab is permitted for wear for the remainder of a military career, even if an individual is not actively assigned to a Ranger unit. The cloth version of the Tab is worn on the battle dress and class A uniform in the Army, and a smaller, metal version is worn on the more formal dress blue and dress mess uniforms.

The Ranger Tab is very similar in design to the U.S. Army's Special Forces Tab and also to the Sapper Tab.
