The 2018 Ping An Chinese Football Association Super League (Chinese: 2018中国平安中国足球协会超级联赛) was the 15th season since the establishment of the Chinese Super League. The league title sponsor was Ping An Insurance. Shanghai SIPG won their first ever top-flight title on 7 November 2018 after their 2–1 victory against Beijing Renhe, ending a historic run for Guangzhou Evergrande Taobao, who had won seven consecutive titles beginning with the 2011 season.

Policy regarding foreign players and U-23 domestic players continued to change in this season. At least one domestic player who is under the age of 23 (born on or after 1 January 1995) must be in the starting eleven, the same as in the 2017 season. However, two foreign-player policies have changed: (1) the number of foreign players on a club's roster has been reduced from five to four and (2) the total number of foreign players under contract with a club in a season has been reduced from seven to six. In addition, a new policy affecting both foreign players and U-23 domestic players has been introduced: The total number of foreign players appearing in matches must be no more than the total number of U-23 domestic players. Players from AFC countries no longer hold a special slot. But clubs can register one non-naturalized player from the Hong Kong Football Association, Macau Football Association or Chinese Taipei Football Association (except goalkeepers) as a native player. According to the Chinese FA, a non-naturalized player is a player who was first registered as a professional footballer in one of the three aforementioned football associations. For still more complexity concerning non-naturalized players, players from Hong Kong and Macau must be passport holders of the Hong Kong SAR or the Macau SAR, and players from Taiwan must be citizens of Taiwan. Policy of U-23 domestic players was relaxed in August for the 2018 Asian Games. It existed in name only from October when China U-25 training team was organized.

Clubs promoted from 2017 China League One

Clubs relegated to 2018 China League One

Beijing Renhe and Dalian Yifang return to the division after a 2-year absence and a 3-year absence respectively. Liaoning Whowin were relegated after an 8-year spell in the Chinese top-flight, while Yanbian Funde were relegated to China League One after spending 2 seasons in the Chinese Super League.

Clubs can register a total of six foreign players over the course of the season, but the number of foreign players allowed on each CSL team at any given time is limited to four. A maximum of three foreign players can be fielded in each match. In addition, each club can register a Hong Kong, Macau, or Taiwan player of Chinese descent (excluding goalkeepers), provided that he registered as a professional footballer in one of those three association for the first time, as a native player.

To preserve chronological evolvements, any postponed matches are not included to the round at which they were originally scheduled, but added to the full round they were played immediately afterwards. For example, if a match is scheduled for round 7, but then played between rounds 8 and 9, it will be added to the standings for round 8.

The awards of 2018 Chinese Super League were announced on 21 November 2018.
