《当哈利遇到莎莉》（英语：When Harry Met Sally…）是一部于****年上映的爱情喜剧片，由诺拉·艾芙伦编剧，罗伯·莱纳执导，比利·克里斯托和梅格·瑞安分别扮演男、女主角哈利和莎莉。故事围绕着两位主角对于男女关系反复地探讨和争论来展开，提出了一个这样的问题：“男人和女人真的可以只是朋友吗？”片中的许多有关双性关系的看法之后也成为家喻户晓的话题，如“高维修”女友和“过渡人士”等。

电影起初的灵感来自莱纳离婚后的单身生活。艾芙伦对莱纳的一次采访成为哈利一角的基础。莎莉则是以艾芙伦和她的一些朋友为蓝本。克里斯托加入后对剧本提出了自己的建议，增强了哈利一角的喜剧效果。艾芙伦在剧本中写下的许多台词都是来源于莱纳和克里斯托在现实生活中的一些对话。电影配乐由马克·施艾曼编排大乐团和管弦乐团演奏，小亨利·康尼克表演，后者因此获得了自己的首座葛莱美奖。

When Harry Met Sally… is a **** American romantic comedy film written by Nora Ephron and directed by Rob Reiner. It stars Billy Crystal as Harry and Meg Ryan as Sally. The story follows the title characters from the time they meet just before sharing a cross-country drive, through twelve years or so of chance encounters in New York City. The film raises the question "Can men and women ever just be friends?" and advances many ideas about relationships that became household concepts, such as those of the "high-maintenance" girlfriend and the "transitional person".
