Off spin is a type of finger spin bowling in cricket. A bowler who uses this technique is called an off spinner. Off spinners are right-handed spin bowlers who use their fingers to spin the ball. Their normal delivery is an off break, which spins from left to right (from the bowler's perspective) when the ball bounces on the pitch. For a right-handed batsman, this is from his off side to the leg side (that is, towards the right-handed batsman, or away from a left-handed batsman). The ball breaks away from the off side, hence the name 'off break'.

Off spinners bowl mostly off breaks, varying them by adjusting the line and length of the deliveries. Off spinners also bowl other types of delivery, which spin differently. Aside from these variations in spin, varying the speed, length and flight of the ball are also important for the off spinner.

The bowler with the most wickets in the history of both Test matches and ODIs, Muttiah Muralitharan, was an off spinner.
