克拉彭公交车上的人（the man on the Clapham omnibus）是一个假设的模型。在英国法里，法院通过该模型判断案件当事人的行为是否符合理性人标准。尤其对于过失侵权的民事诉讼。克拉彭公交车上的人是一位有教养的、智能而又聪颖的普通人。被告的行为将以此标准予以检验。法官格里尔LJ （Greer LJ）在霍尔诉布鲁克兰兹赛车俱乐部一案中（Hall v. Brooklands Auto-Racing Club (1933) 1 KB 205）运用了这个概念，即被告应当符合注意标准以防被确认存在过失。

The man on the Clapham omnibus is a hypothetical ordinary and reasonable person, used by the courts in English law where it is necessary to decide whether a party has acted as a reasonable person would – for example, in a civil action for negligence. The man on the Clapham omnibus is a reasonably educated and intelligent but nondescript person, against whom the defendant's conduct can be measured.
