The Central Bureau of Investigation and Statistics (CBIS; Chinese: 中國國民黨中央執行委員會調查統計局; pinyin: Zhōngguó Guómíndǎng Zhōngyāng Zhíxíng Wěiyuánhuì Diàochá Tǒngjì Jú, commonly known as Zhongtong (Chinese: 中統), was an intelligence unit under the Organisation Department of the Central Executive Committee of the Kuomintang. It was one of Chiang Kai-shek's two police and military intelligence agencies, the other being the Military Bureau of Investigation and Statistics headed by Dai Li from 1929 until his death in 1946. The CBIS focused on civilian intelligence, while the MBIS targeted military activities.
The CBIS bureau was largely superseded by the Ministry of Justice Investigation Bureau in Taiwan after 1949.
