This volume constitutes the thoroughly refereed post-conference proceedings of the 5th International Conference on Verified Software: Theories, Tools, and Experiments, VSTTE 2013, held in Menlo Park, CA, USA, in May 2013. The 17 revised full papers presented were carefully revised and selected from 35 submissions. The papers address a wide range of topics including education, requirements modeling, specification languages, specification/verification case-studies, formal calculi, software design methods, automatic code generation, refinement methodologies, compositional analysis, verification tools, tool integration, benchmarks, challenge problems, and integrated verification environments.
