The iFM conference series seeks to further research into the combination of di?erent formal methods, both for modelling and analysis, covering all aspects from language design over veri?cation techniques to tools and their integration into software engineering practice. iFM 2009 received 55 submissions. Each submission was reviewed by at least three programme committee members. The submissions coveredthe whole sp- trum of integrated formal methods, ranging from formal and semiformal m- elling notations, semantics, veri?cation, re?nement and model transformations to type systems, logics, tools and case studies. The committee decided to accept 21 papers. The programme also included invited talks by David Basin, Michael Butler and Byron Cook. Collocated with the conference were two workshops (on "Integration of Model-based Methods and Tools" and "Formal Methods for SOA and Internet of the Future") and one tutorial (on "Contract Speci?cation and Checking: Application to .NET and C") given by Shuvendru Lahiri and Francesco Logozzo (both from Microsoft Research). We are grateful to all those involved in organizing the conference, producing the proceedings, reviewing the papers, and to the speakers and the attendees of iFM 2009. We also appreciate the support of EasyChair for managing the submission process.
