This document includes the Proceedings of the 11th International Workshop "What can FCA do for Artificial Intelligence?" (FCA4AI 2023), co-located with IJCAI 2023 held in Macao, China. The objectives of the workshop are to investigate issues such as, e.g., how can FCA support various AI activities (knowledge discovery, knowledge engineering, machine learning, data mining, information retrieval, recommendation...), how can FCA be extended in order to help AI researchers to solve new and complex problems in their domains, and how FCA can play a role in current trends in AI such as explainable AI and fairness of algorithms in decision making.
