《开始邮政》（英语：Going Postal）是英国作家泰瑞·普莱契写的第33本碟形世界（Discworld）系列小说，出版于2004年9月25日。跟以往碟形世界系列小说不同，《开始邮政》分成许多章节，这种方式以往只出现在童书跟碟形世界的科学（Science of Discworld）系列中。每章前面都有一段哲学梗概，类似维多利亚时代文学的小说，尤其是儒勒·凡尔纳的作品。 这本书同时入围星云奖跟轨迹奖的最佳奇幻小说。 原本有机会入围雨果奖，由于普莱契担心得奖压力会影响他参加世界科幻大会 的乐趣，所以选择退出。

Going Postal is Terry Pratchett's 33rd Discworld novel, released in the United Kingdom on 25 September 2004. Unlike most of Pratchett's Discworld novels, Going Postal is divided into chapters, a feature previously seen only in Pratchett's children's books and the Science of Discworld series. These chapters begin with a synopsis of philosophical themes, in a similar manner to some Victorian novels and, notably, to Jules Verne stories. The title refers to both the contents of the novel, as well as to the term 'going postal'.
