Over the last few decades we have witnessed a fundamental change in government activity driven by Information and Communication Technologies, storage technologies, the Internet, Web 2.0 & 3.0 technologies and mobile technologies. These technologies are helping governments transform and innovate across all areas of government activity. These proceeding provide a snapshot of current e-Government case studies, re-search, analysis and activity around the World representing cutting edge innova-tion and transformation of government service provision, government transpar-ency, engagement with citizens and business, and the running of government itself. As such these proceeds will provide a valuable contribution to researchers and practitioners interested in e-Government activity. These proceedings represent the work of researchers participating in the 15th European Conference on e-Government - ECEG 2015 which is being hosted this year by The University of Portsmouth, UK on the 18-19 June 2015. ECEG is a recognised event on the European research conferences calendar and provides a valuable platform for individuals to present their research findings, display their work in progress and discuss conceptual advances in the area of e-Government. It provides an important opportunity for researchers and managers to come together with peers and share their experiences of using the varied and expanding range of e-Government available to them.
