List of Catholic dioceses in China

The Catholic Church in Greater China comprises 152 Latin jurisdictions:

21 ecclesiastical provinces, consisting of 21 metropolitan archdioceses and 101 suffragan dioceses
28 apostolic prefectures
1 exempt diocese, the Diocese of Macau
1 apostolic administration, the Apostolic Administration of Harbin

Furthermore, the Eastern Catholic Russian Greek Catholic Church has an exempt apostolic exarchate for China in Harbin.
There is an apostolic nunciature as papal diplomatic representation to China, in Taipei, the seat of government of the Republic of China on Taiwan, also charged with mainland China, Hong Kong and Macau.
The Catholic Church recognizes the Republic of China as the sole government for all of China; nevertheless, it does not recognize all of its territorial claims. In this context, the term "China" is understood as including Hong Kong, Macao, and Taiwan in its 1949 provincial boundaries and mainland China as effectively controlled by the People's Republic of China. Due to the non-recognition of the People's Republic of China, however, the authority of the Taipei-based Chinese Regional Bishops' Conference is effectively limited to the islands of Taiwan, Penghu, Kinmen and Matsu. The dioceses of Hong Kong and Macao do not belong to that conference. The dioceses of mainland China take part in the Beijing-based Chinese Bishops Conference, which is not recognized by the Holy See.

Current Latin dioceses in Greater China

Note that the diocese of Hong Kong belongs to the Ecclesiastical Province of Guangzhou, whereas the diocese of Macau is exempt. Also note that a small part of the diocese of Xiamen, the island of Kinmen, is administered by the Republic of China. At this moment, this part of the diocese is administered by the archdiocese of Taipei.
In all of greater China, only one non-Latin jurisdiction exists: an apostolic exarchate of the Russian Greek Catholic Church in Harbin. It has, however, been vacant since 1939.

However, the Chinese government has its own division of the dioceses, which is not necessarily identical to that of the Holy See. For example, many dioceses have been merged, and the difference between archdioceses, dioceses, apostolic prefectures and apostolic administrations has been abolished. Thus, according to the Chinese government, mainland China is divided into 104 jurisdictions, all dioceses.
Originally, the ecclesiastical provinces were closely aligned with the civil provinces of China. However, the borders of most provinces have not been redrawn again for decades. As a general guideline, however, the ecclesiastical provinces largely correspond with the following civil provinces:

Anqing	Anhui	4	1
Beijing	Beijing, Hebei, Tianjin	15	12
Changsha	Hunan	9	1

Total		152	104

The ecclesiastical jurisdictions in Hainan, Macao, Qinghai and Xinjiang are all exempt, though Macao is a diocese. Heilongjiang is also exempt, being administered by three apostolic prefectures, with the exception of some parts of Mudanjiang, which belong to the Roman Catholic Diocese of Yanji, which is located in Jilin province.
In the Apostolic Constitution of 11 April 1946, all provinces are named by the name of the civil province as well as by the name of the archdiocese. The province of Suiyuan is described as the province of Mongolia, and the province of Shenyang as the province of Manchuria. However, these two names are not used anymore.

Dioceses according to the Chinese Patriotic Catholic Association

The structure of dioceses of the CPCA is not the same one as that of the Holy See. First of all, the distinction between archdioceses, dioceses, apostolic prefectures and apostolic administrations is not maintained: only dioceses exist. Secondly, the dioceses are structured according to the administrative divisions of the PRC. Many dioceses have been merged; some provinces are only served by a single diocese. Except for the diocese of Kangding, which also covers Tibet, all dioceses are restricted to territory within a single province.
In total the CPCA has 104 dioceses, whereas according to the Holy See, mainland China has 143 jurisdictions. In the course of time, the CPCA has established five new dioceses (the Diocese of Jincheng and the Diocese of Xinzhou in Shanxi, the Diocese of Bayannur and the Diocese of Baotou in Inner Mongolia, and the Diocese of Zhanjiang in Guangdong. Forty-four other jurisdictions have been merged with other dioceses. For example, according to the Holy See, Hunan province exists of one archdiocese, three dioceses and four apostolic prefectures. These eight jurisdictions have all been merged by the CPCA to form a single diocese of Hunan. Furthermore, many dioceses have been renamed or have had their seat relocated to a nearby city; most of the dioceses boundaries have also been redrawn to correspond with current PRC administrative divisions. In general, Chinese prefectures have no more than one diocese, but there are exceptions: the prefecture of Baoding is divided in the Diocese of Baoding and the Diocese of Anguo.
This results in the following list of dioceses:
The CPCA has abolished and merged:
3 jurisdictions in Anhui
2 jurisdictions in Fujian
3 jurisdictions in Guangxi
2 jurisdictions in Guizhou
4 jurisdictions in Hebei
3 jurisdictions in Heilongjiang
6 jurisdictions in Hebei
7 jurisdictions in Hunan
1 jurisdiction in Inner Mongolia
2 jurisdictions in Jiangsu
4 jurisdictions in Jiangxi
2 jurisdictions in Jilin
3 jurisdictions in Liaoning
2 jurisdictions in Shandong
In total, 44 Holy See jurisdictions have been abolished and merged. This includes 26 out of 93 dioceses and 18 out of 29 apostolic prefectures.
The CPCA has established:
1 jurisdiction in Guangdong
2 jurisdictions in Inner Mongolia
2 jurisdictions in Shanxi
In total, 5 new CPCA jurisdictions have been established, all dioceses. Apart from these 5, the CPCA has also established a new diocese in Hebei, the Diocese of Chengde, but this diocese was recognized by the Holy See in 2018.
In the following provinces, no new dioceses were established and existing dioceses were not abolished: Beijing, Chongqing, Gansu, Hainan, Henan, Ningxia, Qinghai, Shaanxi, Shanghai, Sichuan, Tianjin, Tibet, Xinjiang, Yunnan and Zhejiang. In Guangdong and Zhejiang, no dioceses were abolished, but new diocese were established.
However, names of dioceses may have been changed, dioceses may have been elevated, and the boundaries of dioceses may have changed.
