Chiefdom of Chuchen (Tibetan: ཆུ་ཆེན་, Wylie: chu chen; Chinese: 促侵土司; pinyin: Cùqīn Tǔsī), also known as Rabden or the Chiefdom of Greater Jinchuan (Chinese: 大金川土司; pinyin: Dà Jīnchuān Tǔsī; Tibetan: ཏ་གྱིན་ཆྭན་ཐུའུ་བསི), was an autonomous Gyalrong Tusi chiefdom that ruled Greater Jinchuan (present day Jinchuan County, Sichuan) during the Qing dynasty.

The first Chuchen chieftain was Slob Dpon, he was appointed by the Qing dynasty in 1723.

Slob Dpon married a daughter to Tsewang, the chieftain of Tsanlha.

Slob Dpon deposed Tsewang and annexed Tsanlha in 1746; then, he invaded neighbouring chiefdoms.

The Chiefdom of Chuchen was abolished, the Qing dynasty started to rule this area directly.
