In basketball, a flagrant foul is a serious personal foul. It is considered flagrant if it involves too much or too violent contact that can injure another player. A flagrant foul may or may not be intentional. In the NCAA, if intentional, a flagrant foul is called an "intentional foul".
The NBA made a flagrant foul rule in the 1990s. It is intended to stop contact which puts a player's safety and health at risk. In the NBA, Flagrant 1 and Flagrant 2 are fouls. A player who commits a flagrant 2 foul must immediately leave the game.
Flagrant fouls can also be punished with fines.
