The First Workshop on High Energy Spin Physics chaired by Prof. L.I. Lapidus was held in Dubna more then 30 years ago. This was followed by the series of biennial workshops in the odd years. The recent one was in Dubna on September 20-24, 2011. The Proceedings of the workshop with talks are available from the Publishing Department of JINR at http://www1.jinr.ru/Proceedings/Proceedings_index.html and at site of DSPIN-11 http://theor.jinr.ru/~spin/2011/. The XV Workshop will take place in Dubna on September 17-21, 2013 under the sponsorship of JINR and the International Committee for High Energy Spin Physics as a joint Dubna-Prague-Warsaw Workshop. We hope that it offers an opportunity to a large group of physicists and students from Russia and other JINR Member States to get acquainted with the most recent experimental and theoretical results in the spin physics. About 100 scientists from different research centers are expected to participate.
