These are the proceedings of the 10th International Workshop on Compu- tional Logic in Multi-Agent Systems (CLIMA-X), held September 9 10, 2009 in Hamburg, co-located with MATES. The purpose of the CLIMA workshops is to provide a forum for discussing techniques, based on computational logic, for representing, in a formal way, programming and reasoning about agents and multi-agent systems.
