The 2022–23 Hong Kong FA Cup is the 48th edition of the Hong Kong FA Cup. 10 teams entered this edition. The competition is only open to clubs who participate in the 2022–23 Hong Kong Premier League, with lower division sides entering the Junior Division, a separate competition. The winners of this year's FA Cup will qualify for the 2023–24 AFC Champions League qualifying play-off.

Since the previous edition of the FA Cup was cancelled due to COVID-19 pandemic in Hong Kong, Eastern, the champions of the 2019–20 Hong Kong FA Cup remain the defending champions of the competition, but were eliminated in the semi-finals.

Kitchee became the champions for the seventh time after beating Rangers in the final.

As the 2022–23 Hong Kong Premier League title holders, Kitchee has qualified for the 2023–24 AFC Champions League group stage as league winners. The 2023–24 AFC Champions League qualifying play-off position went to the third-placed HKPL team Rangers.
