This volume contains the proceedings of the 17th European Conference on Logics in Artificial Intelligence, which was to take place at the University of Klagenfurt, Austria, but due to the COVID-19 pandemic was held as an online event during May 1720, 2021.

The European Conference on Logics in Artificial Intelligence (or Journes Europennes sur la Logique en Intelligence ArtificielleJELIA) began back in 1988, as a workshop, in response to the need for a European forum for the discussion of emerging work in this field. Since then, JELIA has been organized biennially, with proceedings published in the Springer series Lecture Notes in Artificial Intelligence. Previous meetings took place in Roscoff, France (1988), Amsterdam, The Netherlands (1990), Berlin, Germany (1992), York, UK (1994), vora, Portugal (1996), Dagstuhl, Germany (1998), Mlaga, Spain (2000), Cosenza, Italy (2002), Lisbon, Portugal (2004), Liverpool, UK (2006), Dresden, Germany (2008), Helsinki, Finland (2010), Toulouse, France (2012), Madeira, Portugal (2014), Larnaca, Cyprus (2016), and Rende, Italy (2019).

The aim of JELIA is to bring together active researchers interested in all aspects concerning the use of logics in artificial intelligence to discuss current research, results, problems, and applications of both theoretical and practical nature. JELIA strives to foster links and facilitate cross-fertilization of ideas among researchers from various disciplines, among researchers from academia and industry, and between theoreticians and practitioners. The scientific community has been increasingly showing interest in JELIA, which during the years featured the growing participation of researchers from outside Europe and a very high overall technical quality of contributions; hence, the conference turned into a major biennial forum and a reference for the discussion of approaches, especially logic-based, to artificial intelligence.

JELIA 2021 received 68 submissions in two different formats (long and short papers). Throughout the reviewing process, at least three Program Committee members took care of each work. Out of the 68 submissions, 27 long and 3 short papers were accepted, amounting to an acceptance rate of 44%, which is comparable to previous JELIA conferences. Of the accepted papers, 13 were declared to be student papers (21 submitted), 5 to be system papers (6 submitted), and 1 to be an application paper (4 submitted) by the authors upon submission.

We would like to thank the members of the Program Committee and the additional reviewers for their efforts to produce fair and thorough evaluations of the submitted papers, the local organization committee, and of course the authors of the scientific papers, including those not accepted for publication. The quality of the contributions was very high, which is the essential ingredient for a successful scientific conference.

The conference program included invited talks by Thomas Eiter, Esra Erdem, and Alessandra Russo, and had prizes for the Best Paper and Best Student Paper, each received a prize money of EUR 500, kindly offered by Springer. We are grateful to all sponsors for their generous support: Frderverein Technische Fakultt, Springer, and of course the University of Klagenfurt. Last, but not least, we thank the people of EasyChair for providing resources and a marvellous conference management system.
