In the game of cricket, a googly refers to a type of delivery bowled by a right-arm leg spin bowler. It is different from the normal delivery for a leg-spin bowler in that it is turning the other way. The googly is not a variation of the typical off spin type of delivery, in that the cricket ball is presented from the bowler's hand in such a way that once the ball pitches; instead, it deviates in the opposite direction of a leg spinning type of delivery. It has also been colloquially referred to as the wrong'un, Bosie or Bosey, with the latter two eponyms referring to Bernard Bosanquet, the bowler who originally devised and began using the googly.

A delivery or ball in cricket is a single action of bowling a cricket ball toward the batter. Once the ball has been delivered, batters may attempt to score runs, with the bowler and other fielders attempting to stop this by getting the batters out. When the ball becomes dead, the next delivery can begin.
