I would like to thank the Program Committee chairs of the different events for their help and cooperation during the preparation of the conference, and the Steering Committee and Advisory Boards of DisCoTec and its conferences for their guidance and support. The organization of DisCoTec 2021 was only possible thanks to the dedicated work of the Organizing Committee, including Caroline Caruana and Jasmine Xuereb (publicity chairs), Duncan Paul Attard and Christian Bartolo Burlo (workshop chairs), Lucienne Bugeja (logistics and finances), and all the students and colleagues who volunteered their time to help. I would also like to thank the invited speakers for their excellent talks. Finally, I would like to thank IFIP WG 6.1, EAPLS and the Microservices Community for sponsoring this event, Springers Lecture Notes in Computer Science team for their support and sponsorship, EasyChair for providing the reviewing framework, and the University of Malta for providing the support and infrastructure to host the event.

This volume contains the papers presented at COORDINATION 2021, the 23rd International Conference on Coordination Models and Languages, organized online by the University of Malta in Valletta during June 1418, 2021, as part the federated DisCoTec conference.

The COORDINATION conference provides a well-established forum for the growing community of researchers interested in coordination models and languages, architectures, verification, and implementation techniques necessary to cope with the complexity induced by the demands of todays software development. For the third year in a row, COORDINATION has called for tool papers describing experience reports, technological artefacts, and innovative prototypes, as well as educational tools in the scope of the research topics of the conference. Tool papers were selected according to the combination of an extended abstract and a short video demonstration, after which full papers were produced to be included in these proceedings following a light-weight review. In addition, seeking to further reinforce the practical applicability aspects of the COORDINATION community research, we have explicitly included among the topics of interest the industry-led efforts in coordination and industrial case studies.
