The Ministry of Posts and Communications or Youchuanbu (Chinese: 郵傳部; pinyin: Yóuchuánbù) was a late Qing dynasty ministry responsible for mail and telecommunications and for the Chinese rail network. It was established in 1906 through the unification of the Imperial Railroad of North China and other railroads with the postal administration and the recently nationalized Imperial Chinese Telegraph Administration. After the 1911 revolution gave its name to the Communications Clique during the Warlord Era.
