阻碍防守是在板球运动中罕见的出局方式。

第37条板球规则规定：

任一击球员如果故意地阻碍防守或通过语言以及行动使对方分心都会以阻碍防守而被判出局。如果任一击球员在没有获得外野手同意的情况下，在外野手触到球之后，故意地用球拍或者身体击打球，而不是用没有握球拍的手击打，那幺这也将被视为阻碍防守

如果妨碍是事故性的，那就不算是故意的，因此，击球员也不能因为阻碍防守而被判出局。 此法规的第3段规定：

如果任一击球员想要阻止接杀而引起的妨碍或者使对方分心那幺击球者出局。依据第34.3条法则（合法击球一次以上），即使击打者在合法保卫自己的三柱门的时候造成妨碍也同样算是阻碍防守。

Obstructing the field is one of the ten methods of dismissing a batsman in the sport of cricket. It dictates that either batsman can be given out if he wilfully attempts to obstruct or distract the fielding side by word or action. It is governed by Law 37 of the laws of cricket, and is a rare way for a batsman to be dismissed: in the history of cricket, there have been only one instance in Test matches and six occasions in One Day International (ODI) games. In most cases this occurs when a batsman thinks that he is going to be run out and he blocks the ball with his bat or changes his line when running between wickets to block the ball. It is legal to block the ball if, when a batsman is running between wickets, he does not deviate from his course and the ball hits him without the batsman blocking the ball on purpose. It is the sole responsiblity of the batsman to not even touch the fielder while catching the ball.
