This volume is the ?fth in a series that started in 2005, collecting papers from the Coordination, Organizations, Institutions and Norms (COIN) Workshops. The papers in this volume are drawn from the three meetings that took place in 2009. AAMAS COIN@AAMAS 2009 took place on May 12, 2009, as a satellite event of the 8th International Conference on Autonomous Agents and Multiagent Systems (AAMAS 2009), in Budapest, Hungary. With 35 registered participants, the workshop was an exciting and fruitful gathering where discussions followed the papers presented by an international group of speakers. We had participants from Australia, Italy, The Netherlands, New Zealand, Portugal, Spain, UK and USA, to name a few. Of the 19 submissions, 12 were selected for presentation and,subsequently,10 wereinvitedto be revisedandincluded inthe proceedings.

We had 15 submissions, 10 of which were selected for presen- tion at the workshop. The workshop sessions gave rise to a stimulating and p- ductive gathering with an invited talk from Maarten Sierhuis of NASA entitled “TowardsOrganization-AwareMulti-Agent Systems,” followed by presentations of accepted papers. An international audience from countries such as Australia, Brazil, India, Canada, Spain, France, UK and USA participated in the wo- shop. From the 10 presented papers, 6 were invited to be revised and included in the proceedings.
