郵政式拼音係一套中文拉丁化嘅方案，專門用喺中國地名。始於晚清，1906年春喺上海舉行嘅帝國郵電聯席會議通過使用呢套方案。呢個方案統一並規範咗中國地名嘅拉丁字母轉寫方法。帝國郵電聯席會議決定，基本上以翟理斯編寫嘅《華英字典》（1892年上海初版）入邊嘅拉丁字母拼寫法為依據。而《華英字典》所用嘅拼寫方法實際上係威妥瑪拼音。為咗方便𢬿來打電報，會議決定唔採用任何附加符號（譬如送氣符號）。
Post-style pinyin is a set of Latinization schemes for Chinese, which are used exclusively in Chinese place names. Beginning in the late Qing Dynasty, the Imperial Joint Conference on Posts and Telecommunications held in Shanghai in the spring of 1906 used this scheme. This scheme unifies and standardizes the method of transliterating the Latin alphabet of Chinese place names. The Imperial Joint Conference of Posts and Telecommunications decided to base it on the Latin spelling of the Chinese alphabet in the Chinese-English Dictionary (first edition in Shanghai in 1892) compiled by Zhai Lis. And the spelling method used in the Chinese-English Dictionary is actually the Wittoma Pinyin. In order to facilitate the incoming telegrams, it was decided not to use any additional symbols (e.g. aspirated symbols).
