The flag route, also known as a corner route, is a pass pattern in which the receiver begins by running vertically for 10-12 yards before breaking at a 45 degree angle toward the sideline.

The mirror to the post route, the flag route is commonly used, but it is a more difficult throw for a quarterback.  It is often used to defeat Cover 2 coverage and as part of a smash or flood concept.
