The issue is related to the 13th International Symposium on Orthogonal Polynomials, Special Functions and Applications (OPSFA13), held at the National Institute of Standards and Technology (NIST), Gaithersburg, Maryland, USA, June 1–5, 2015. The issue contains papers from participants of the meetings but also from others whose work fits into the topics of the symposium. Four of the plenary speakers wrote a contribution for this special issue (Charles Dunkl, Mourad Ismail, Teresa Pérez, and Wadim Zudilin) and there is a report from the open problem session of OPSFA-13. There are 28 papers with a total of 555 pages. We would like to thank the chairs of the scientific committee of OPSFA-13, and in particular Daniel W. Lozier of NIST, for the organization of the meeting.

We are grateful to all the authors who have published papers in the issue, and give our special thanks to all the referees for providing constructive reviews.
