Kangaroo Court，袋鼠法庭，或非法法庭、私设之法庭，即非正规的法庭。也指私设公堂或不合法律规程和正常规范的审判。

西方法律术语。来源有多种说法。一说此语首次以书面形式出现于淘金热时代的美国加利福尼亚地区。二说这类情形涉及澳大利亚早期的开矿或者非法侵占矿藏（jumping mining claims）事件。澳大利亚素有袋鼠之乡的称呼，因而这类诉讼与袋鼠扯上了关系。

Kangaroo Court（《朗文当代高级英语辞典》）：

1)a mock court set up without legal basis, such as a fraternity, sports team or army squad might set up to punish minor violations of organizational decorum.

2)slang for a court of law in which the violations of procedure, precedents, and due process are so gross that fundamental justice is denied. It usually means that the judge is incompetent or obviously biased.

袋鼠法庭有两个类型：

一种是专门歪曲法律原则和公正精神的模拟法庭游戏；

另一种则是不负责任、没有权威、根本不符合法律规范的法庭审判。
