Run out is a method of dismissal in the sport of cricket. It is governed by Law 38 of the Laws of cricket.

Run-out or runout is an inaccuracy of rotating mechanical systems, specifically that the tool or shaft does not rotate exactly in line with the main axis. For example; when drilling, run-out will result in a larger hole than the drill's nominal diameter due to the drill being rotated (off axis instead of in line). In the case of bearings, run-out will cause vibration of the machine and increased loads on the bearings.
