The touch-line is the line on either side of the playing area of a games of rugby league, rugby union and association football. In many other sports it is called a side-line.
The continuation of the touch-line beyond the goal line ending at the dead ball line is called the "touch-in-goal line". In rugby union the two touch-lines may not be more than 70 metres (230 ft) apart and they are not part of the playing area (Law 1).
- The area beyond the touch-line is touch.
- The officials who monitor the touch-lines are the touch judges.
