2022 AFC Champions League

The 2022 AFC Champions League was the 41st edition of Asia's premier club football tournament organized by the Asian Football Confederation (AFC), and the 20th under the current AFC Champions League title.

This edition was the last in an all-year-round (spring-to-autumn) schedule despite actually being held from 2022 to 2023; from the next season onwards, the competition switched to an autumn-to-spring schedule.

This edition saw increase in numbers of preliminary players registration with 35 players, up from 30 in previous editions. This paved the way for more foreign players to be included in squad, although the AFC "3+1" foreign players rule was in effect during the match.

Due to the emerging complications caused by the Omicron variant of COVID-19 and the associated risks, as well as the unique circumstances surrounding the football schedule before and after the 2022 FIFA World Cup, it was confirmed that the final, originally scheduled for October 2022, would not be completed until May 2023. As the 2022 FIFA Club World Cup would already be held by that time, the AFC confirmed on 23 December 2022 that Al-Hilal would be their representative at the 2022 FIFA Club World Cup as the reigning champions from the 2021 AFC Champions League.

Al-Hilal of Saudi Arabia were the defending champions. Urawa Red Diamonds defeated Al-Hilal 2–1 on aggregate in the final to win their third title. As Asian champions, they automatically qualified for the 2023–24 AFC Champions League qualifying play-offs since they did not qualify through their domestic performance. In addition, they earned the right to play in both the 2023 FIFA Club World Cup in Saudi Arabia and the 2025 FIFA Club World Cup in the United States.

2021 AFC Cup winners Al-Muharraq, having not obtained an AFC license, were not eligible to participate in this edition.

Association team allocation
The 47 AFC member associations are ranked based on their clubs' performance over the last four years in AFC competitions (their national team's FIFA World Rankings no longer considered). The slots are allocated by the following criteria according to the Entry Manual:
 * The associations are split into two regions (Article 3.1):
 * West Region consists of the 25 associations from the West Asian Football Federation (WAFF), the South Asian Football Federation (SAFF), and the Central Asian Football Association (CAFA).
 * East Region consists of the 22 associations from the ASEAN Football Federation (AFF) and the East Asian Football Federation (EAFF).
 * The AFC may reallocate one or more associations to another region if necessary for sporting reasons.
 * The top 12 associations in each region are eligible to enter the AFC Champions League.
 * In each region, there are five groups in the group stage, including 16 direct slots, with the 4 remaining slots filled through qualifying play-offs (Article 3.2). The slots in each region are distributed as follows:
 * The associations ranked 1st and 2nd are each allocated three direct slots and one play-off slot.
 * The associations ranked 3rd and 4th are each allocated two direct slots and two play-off slots.
 * The associations ranked 5th are each allocated one direct slot and two play-off slots.
 * The associations ranked 6th are each allocated one direct slot and one play-off slot.
 * The associations ranked 7th to 10th are each allocated one direct slot.
 * The associations ranked 11th and 12th are each allocated one play-off slot.
 * The AFC Champions League title holders and AFC Cup title holders are each allocated one play-off slot should they not qualify for the tournament through domestic performance (Article 3.6). The following rules are applied:
 * If the AFC Champions League title holders or AFC Cup title holders are from associations ranked 1st to 6th, their association is allocated the same number of play-off slots, and they replace the lowest-seeded team from their association. Otherwise, their association is allocated one additional play-off slot, and they do not replace any team from their association (Articles 3.8, 3.9 and 3.10).
 * If both the AFC Champions League title holders and AFC Cup title holders are from the same association which is allocated only one play-off slot, their association is allocated one additional play-off slot, and only the lowest-seeded team from their association is replaced as a result (Article 3.11).
 * The AFC Champions League title holders and AFC Cup title holders are the lowest-seeded teams in the qualifying play-offs if they do not replace any team from their association (Article 3.12).
 * If any association ranked 1st to 6th do not fulfill any one of the AFC Champions League criteria, they have all their direct slots converted into play-off slots. The direct slots given up are redistributed to the highest eligible association by the following criteria (Articles 3.13 and 3.14):
 * For each association, the maximum number of total slots is four and the maximum number of direct slots is three (Articles 3.4 and 3.5).
 * If any association ranked 3rd to 6th is allocated one additional direct slot, one play-off slot is annulled and not redistributed.
 * If any association ranked 5th to 6th is allocated two additional direct slots, one play-off slot is annulled and not redistributed.
 * If any association ranked 7th to 10th do not fulfill any one of the AFC Champions League criteria, they have their direct slot converted into play-off slot. The direct slot given up is redistributed to the next association ranked 11th or 12th, whose play-off slot is annulled and not redistributed, or if neither are eligible, the highest eligible association by the same criteria as mentioned above (Articles 3.16 and 3.17).
 * If any association with only play-off slot(s), including any association ranked 11th to 12th or those mentioned above, do not fulfill the minimum AFC Champions League criteria, the play-off slot(s) are annulled and not redistributed (Articles 3.19 and 3.20).
 * For each association, the maximum number of total slots is one-third of the total number of eligible teams (excluding foreign teams) in the top division (Article 3.4). If this rule is applied, any direct slots given up are redistributed by the same criteria as mentioned above, and play-off slots are annulled and not redistributed (Article 9.10).
 * All participating teams must be granted an AFC Champions League license, and apart from cup winners, finish in the top half of their top division (Articles 7.1 and 9.5). If any association do not have enough teams which satisfy these criteria, any direct slots given up are redistributed by the same criteria as mentioned above, and play-off slots are annulled and not redistributed (Article 9.9).
 * If any team granted a license refuses to participate, their slot, either direct or play-off, is annulled and not redistributed (Article 9.11).
