Catholicism entered Chifeng as early as 1835.

In 1883, the Mongolic Apostolic Vicariate was divided into three. Chifeng fell into the Apostolic Vicariate of Eastern Mongolia, which was renamed into Jehol in 1922.
It was until 1932, the Prefecture Apostolic of Chihfeng (Chifeng) was erected. It was elevated into a diocese in 1949, after which the Church suffered from political turmoil.
After religious activities revived in 1981, six priests who were sent to reform-through-labor returned to the diocese. Father Qiao Zhanying became the diocesan administrator. Since the Church suffered much destruction, they had to start almost from scratch. In 1983, the diocese sent out the first batch of seminarians to Beijing Seminary for formation. Two years later, they sent the second batch to the Seminary in Hohhot, regional capital of Inner Mongolia Autonomous Region. At the same time, they also recovered Church properties and rebuilt new churches. After a decade of effort, the diocese saw much development.
In 1990, Father Andreas Zhu Wenyu was ordained bishop without papal mandate but he reached communion with the Vatican later. He died in 2006.
