国际电信联盟电信标准化部门（英语：ITU Telecommunication Standardization Sector，缩写ITU-T）是国际电信联盟管理下的专门制定远程通信相关国际标准的组织。该机构创建于1993年，前身是国际电报电话咨询委员会（法语：Comité Consultatif International Téléphonique et Télégraphique，英语：International Telegraph and Telephone Consultative Committee，缩写：CCITT），总部设在瑞士日内瓦。

The ITU Telecommunication Standardization Sector (ITU-T) is one of the three sectors (divisions or units) of the International Telecommunication Union (ITU); it coordinates standards for telecommunications.

The standardization efforts of ITU commenced in 1865 with the formation of the International Telegraph Union (ITU). ITU became a United Nations specialized agency in 1947. The International Telegraph and Telephone Consultative Committee (CCITT, from French:Comité Consultatif International Téléphonique et Télégraphique) was created in 1956, and was renamed ITU-T in 1993.
