站台，或称月台，是指路轨傍边高出的台面。一般建筑在铁路车站以方便乘客上下车。

站台原先称作“月台”，原意是「赏月的高台」。中国传统建筑中，大殿、正房前方连接台阶的向前方突出的平台称为“月台”。站在月台上，一般前无遮拦，适于赏月。古人登月台触景生情，心情舒畅，思绪万千，会引发出各种人生感悟，并留下众多诗词佳作：“明从海上来，皎皎入我牖。何如登高台，对月把尊酒”（宋敏）“夜色何苍苍，月明久未上。不上倚城台，无奈东南嶂。”（苏辙）等。

现代月台成为送迎之地，别离时的伤感，重逢时的喜悦，都汇集于此。

A railway platform is a section of pathway, alongside rail tracks at a railway station, metro station or tram stop, at which passengers may board or alight from trains or trams. Almost all rail stations have some form of platform, with larger stations having multiple platforms. The term "platform" has also gained usage as a verb among some rail conductors, as in, "The first two cars will not platform at [station]".
