This volume contains the Technical Communications presented at the 39th International Conference on Logic Programming (ICLP 2023), held at Imperial College London, UK from July 9 to July 15, 2023. Technical Communications included here concern the Main Track, the Doctoral Consortium, the Application and Systems/Demo track, the Recently Published Research Track, the Thematic Tracks on Logic Programming and Machine Learning, and Logic Programming and Explainability, Ethics, and Trustworthiness. The International Conference on Logic Programming (ICLP) is the premiere international scientific venue for presenting, discussing, and disseminating fundamental and applied research in the field of logic programming and in related interdisciplinary areas. The conference was launched in 1982, with its first edition in Marseille, France, and continues to serve the broad international logic programming community. ICLP 2023 was a special edition of the conference as it represented the closing event of the "Year of Prolog" a year-long celebration of the 50th anniversary of the introduction of the Prolog programming language. The conference included a dedicated session to discuss the achievements accomplished throughout the year and the assignment of the 2023 Alan Colmerauer Prize, as well as an event on "Teaching Prolog: the Next 50 Years."
